Cause some of its faces will be overlapping and you'll get some odd artifacts where the further away triangle will show up instead of the closer one. Cause you turned off depth testing.

To properly hack this, you'd have to add a second render objects with ZTest set to LEqual.

[dry willow]

Could do a prior depth-only pass, with vertex shader that adjusts z to far plane or write to SV_Depth, to reset the depth buffer. Then render normally
(this forum post shows the technique)

[hearty tundra]

Yeah. But just binding a separate depth target is simpler and requires to render only once.

[dry willow]

Agreed, but requires coding knowledge and not helpful the APIs keep changing

[iron compass]

this kind of thing typically comes up when drawing fx/ui/gizmos, which typically are transparent anyway, so this is a simple way to achieve the desired effect.

[hearty tundra]

I just never upgrade my projects 😆

[hearty tundra]

Well, this thing also comes up when making game items inspectable and also for body rendering in FPS games 👀

[brisk radish]

I think writing a custom render feature is too complicated for me. So, I wonder if anyone knows which would be more performant:

1. Second overlay camera that only renders the "always on top" layer
2. Render Objects Renderer Feature (documentation)

[haughty garnet]

What are you trying to render on top? If it's like a gun or something so it doesn't clip into your geometry then a second camera usually works fine.

unless you do want that scene lighting then it's probably easier to use render objects

[compact sedge]

i need a hand for my unity shader the shader is pink for some reason even though the color on the shadegraph isnt

[compact sedge]

fixed

[brisk radish]

In Unity 6, they mention URP has gotten performance improvements. Has anyone benchmarked prior version vs Unity 6 to see the performance differences?

[kind swallow]

Not sure if this is the right place to ask but I'll try here first. I've added the ability to change the render scale during run-time to make my game look more pixelated and I've noticed that Render textures (Portals rendering what a camera is viewing) that would normally be rendering at the same resolution as the game appear blurry. If I'm using a shaderpack, there's some colour difference as well. Strangely, this issue doesn't occur in the original portal source code so I suspect it might be something I changed.

I've tried changing adjusting the aniso levels, Filter, Dynamic Scaling, mip maps and Post Processing on the portal cameras and the render textures still appear blurry.
I've provided 4 screenshots to better visualise what's going on. In that screenshot, I changed the materials to standard URP Lit to be sure and it still occurs. The Roof and Floor are where it's most obvious.
What settings would normally cause the blurriness? I'm using Unity 2022.

[cosmic marsh]

I’ve seen many posts and videos showcasing the Unity 6 GPU resident drawer. A quick google search should reveal much. Here is one such link : https://www.youtube.com/watch?v=4Nep73ipIJQ . I don’t have a link handy, but have seen similar videos showcasing the benefits of the new occlusion culling available too. Seems like good performance gains all around for 3D games.

[cloud night]

Hi, for some reason when I paint the terrain with any texture above the 4th layer, it looks fine with no lighting, but when lighting is activated weird artifacts appear, does someone how to fix this?

[marble wing]

Is URP valid for Mobile devices if used properly with the right optimizations?

[soft lion]

Very much so. I'd refer to this page for in depth comparison https://docs.unity3d.com/2021.3/Documentation/Manual/BestPracticeLightingPipelines.html

[stoic cradle]

Hi, I've changed my camera pixelRect to a smaller size, And I want to re-scale it on a later pass, but I dont find the way to tell Unity "This is the new color & depth texture for the camera", What is the way to tell Unity on a pass that this is the outcome?

[rich sierra]

How do I make sure Graphics.RenderMesh() renders always on top (and only once per frame, as I am calling it in an editor script which might get called several times a frame)?

[marble wing]

Thank you very much!

[teal locust]

input system

[full torrent]

making these transparent roads, but a thin line like this always remains. alpha clipping fucks with the texture too much and idk what to do. I import the texture to photoshop and move the eraser in that area with the line, but nothings removed

[soft lion]

Change texture wrap mode from Repeat to Clamp on the texture import settings. It's more than likely that the line is caused by the texture wrapping around the plane to the other side (only happens with bilinear/trilinear filtering but likely you don't want to touch that)

[trim scroll]

This images you sent seem to be working properly. If you’re pixelating, I assume what it’s doing in the background is downsampling the color buffer with no blending. This means the amount of pixelation is the same no matter how far away the geometry is which is what it looks like is happening in your scene.

If you want the distant features to not be as blurry you can try to add some logic that the amount of blurring/influence of the unpixelated undownsampled value is influenced by the depth of the scene

[kind swallow]

hmm, I might need to learn some shader coding sounds like. At least If I understanding what you mean correctly, I'm going to have to edit the Portal Shader to apply the scene depth to the render texture. Thanks for the insight

[swift verge]

Is it possible to re-bind the main light shadow map (ideally without copying it entirely)?

I want to sample the raw depth from it, but certain platforms differentiate between textures bound with a comparison sampler and with a normal sampler.

[elfin escarp]

On the left is the asset URP Stylized Water, which is a shader graph, the avatar skin is also a shader graph, and the gray on the right is a Lit material. Due to my setup, I've got an little bit of an antiliasing issue, which you can see around the hand over the water, and the edge of the gray ground and water. I have the Decal Rendering Feature (for blob shadows) with "Use Rendering Layers" checked (so my character doesn't show shadow). If I disable either, then the antialiasing issue goes, but then I don't have my feature. I don't have Depth Texture checked, but I did try that and it made no difference. Boat Attack water does not have this issue, but it's not a shader graph and not nearly as performant. I tried fiddling with the other settings but to no avail. Anyone have thoughts as to how to fix?

[soft lion]

One easy solution would be to use post processing AA instead of MSAA which causes these extrapolation artifacts (I assume that’s caused by MSAA, could be something else too)

[quick oak]

Hi,
i want to import a material into unity using URP. There is a alpha texture and a displacement texture which i cant assign to any available material input which make it look weird. Does anyone know how to handle these two maps? I thought of using a different shader, currently it is URP/Lit

[marble vigil]

Alpha goes into base texture alpha channel for transparency
URP Lit doesn't support displacement though

Afaik displacement is mostly meant for when you're authoring assets, not that much for in-engine materials

Because in game assets are too low poly for displacement to make a difference, or a positive one at any rate, so you'd rather bake details like those before exporting

It's useful for tessellation but tessellation is not a very popular effect

[quick oak]

Hmm i see thx. I got the material from a 3rd party addon for blender and hoped there is an easy Export-Import way. But of course not

[marble vigil]

It could be a "compatible" material even if it has extra textures/features that won't be needed

[stoic cradle]

using (var builder = renderGraph.AddRasterRenderPass<object>("TTexture copy to Camera.color", out var _, profilingSampler))
{
    builder.UseTexture(temporalTexture, AccessFlags.Read);
    builder.SetRenderAttachment(target, 0, AccessFlags.Write);

    builder.SetRenderFunc((object _, RasterGraphContext rgContext) =>
    {
        Blitter.BlitTexture(rgContext.cmd, temporalTexture, new Vector4(1, 1, 0, 0), 0, false);
    });
}

Does any one knows why the AddRasterRenderPass and examples have an object to "Pass Data"? I dont see any difference with using context variables

[distant pelican]

Does anyone have any idea on why this simple fog RendererFeature script breaks all transparency in the scene and constantly throws

Unity OPENGL NATIVE PLUG-IN ERROR: GL_INVALID_OPERATION: Operation illegal in current state

https://pastebin.com/ZpKLDicK

||Been wasting tens of hours on this, any help would literally mean the world right now ..||

[elfin escarp]

Thanks. Your solution works, but the performance hit might be more that what’s acceptable.

[soft lion]

what you mean by that?

[elfin escarp]

This is running on Quest 2, and switching to post processing AA causes the frame rate to drop more than having MSAA.

[soft lion]

Did you test that yourself? Might be true but FXAA for example should be quite cheap AA method

Hello,I added volume n bloom so an gameobject can glow, but its applying to the skybox sun too. How would I go about removing bloom from skybox and only have the gameobject glow. The 2 camera method didnt work

[soft lion]

I think correctly executed 2 camera method should work though

[wise minnow]

The method I tried was pretty confusing and everywhere I seen said it wouldnt work to begin with. How would I go about this ?

[soft lion]

I can try to do it myself so I can explain if I succeed

[wise minnow]

okay, id highly appreciate it

[soft lion]

Weirdly enough you seem to be right on that, I can't find an easy way to do that. The problem is that once you render the scene with the post processing, it doesn't seem to be possible to render the skybox behind it. With custom shaders it might be possible but unity doesn't seem to offer much help with that. Is this really required though? Wouldn't sun having bloom around it make sense though?

[wise minnow]

yea but Im trying to turn it up on a single object

like a lot and its making the game impossible to see due to the sun of the skybox

[soft lion]

can you show what the object looks like?

[wise minnow]

bottom left is object

[soft lion]

the arrows?

[wise minnow]

yea

[soft lion]

if that's the only object you really need bloom on, you could either fake it (with larger sprite with the bloom baked into it for example) or increase the intensity of those arrows enough so that it exceeds the suns intensity and increase the threshold so that the sun doesn't get affected

[marble vigil]

Even if the objects in the first camera were masked out from the render of the second bloomless sky camera, the bloom itself would be occluded by the sky I'm afraid
Unity 6 has technically some way to do it with Alpha Processing but it's almost entirely undocumented

[soft lion]

figured so

[wise minnow]

i dont think I have that option in my unity version

[marble vigil]

If your unity version is not specifically "6" then no

Even if it was I wouldn't be able to tell how to get that feature working

[fossil arrow]

https://github.com/Math-Man/URP-PSX-FORKED any tutorial for this?

[soft lion]

@wise minnow woukd this work thoughh?

[nocturne bramble]

heyo! I recently upgraded an asset which I created to unity 6 preview (6000.0.18f1) and I am seeing these shadows, in the older version of unity it was looking ok. to get the similar result like the 2022 lts I have to change the Environment Lighting Source to color instead of skybox. have anyone else seen these issues? as unity6 is still in preview this can be a bug?

this is what it should look like (this is how it was looking in the 2022.3.27f1 lts release), to get this result I have changed the Environment Lighting Source to color instead of skybox

[marble vigil]

In Unity 6 environmental lighting from the skybox no longer temporarily auto-generates to avoid confusion about its temporary nature
So to get the same result you need to make a new lighting settings asset and generate lighting
Baked and realtime GI can (and probably should) be disabled for that operation unless you want them as well

[nocturne bramble]

thanks for the info, since I am not making any production software right now, so I should be good to go even with Lighting Source to color, as it does fixed it when I ran baking process for a few hours (low end office laptop, it would takes literal hours baking the lights even with gpu)

[marble vigil]

If you don't need baked lightmapping and disable it, generating the lighting should take only a couple of seconds

[nocturne bramble]

yeah thanks for helping me, it worked perfectly and it didn't took hours on my i3

[pure zinc]

Hello, as you can see, I added a separate camera to make sure that only objects with a specific layer have the glow effect, and I assigned that layer only to the HUD you see above. However, despite this, the entire scene is glowing. I double-checked, and all objects are on the default layer except for the HUD on the canvas. Yet, everything seems to be using the glow effect. What should I do?

if you want i can sent much more detail

[marble vigil]

PP always applies to the whole rendered image
Including cameras rendered before it in the stack, but not ones after

[pure zinc]

soo what should i do there is any way to do this

i only wanted to use the glow effect only spesific layers

i reseacred on internet but there is nothing about that i just found this camera method but also not working

[marble vigil]

To do what precisely?

You can exclude the HUD or other overlay cameras from post processing

But not practically the other way around

[pure zinc]

okey but i only want include the HUD i mean just the HUD part need to be glow

thats why i said is there any other way to do (just make the HUD glow it doesnt matter how i just want to be HUD glowing 🙂 )

[marble vigil]

Not normally possible
Unity 6 added an "alpha processing" feature that could do it but it may require making a custom post processing effect and it's barely documented

[lost basalt]

I am losing my mind

        {

            builder.AllowPassCulling(false);
            UniversalResourceData resourceData = frameData.Get<UniversalResourceData>();

            UniversalCameraData cameraData = frameData.Get<UniversalCameraData>();
            UniversalRenderingData renderingData = frameData.Get<UniversalRenderingData>();
            UniversalLightData lightData = frameData.Get<UniversalLightData>();

            var filterSettings = new FilteringSettings();
            var drawSettings = RenderingUtils.CreateDrawingSettings(new ShaderTagId("Voxelize"), renderingData, cameraData, lightData, SortingCriteria.CommonOpaque);
            var rendererListParams = new RendererListParams(renderingData.cullResults, drawSettings, filterSettings);

            passData.rendererList = renderGraph.CreateRendererList(in rendererListParams);
            
            builder.UseRendererList(passData.rendererList);

            passData.targetBuffer = resourceData.activeColorTexture;
            builder.SetRenderAttachment(passData.targetBuffer, 0);

            var desc = new RenderTextureDescriptor(128, 128, RenderTextureFormat.ARGBHalf, 0, 0);
            desc.dimension = TextureDimension.Tex3D;
            desc.enableRandomWrite = true;

            passData.voxelBuffer = UniversalRenderer.CreateRenderGraphTexture(renderGraph, desc, "Voxel Buffer", true);
            builder.SetRandomAccessAttachment(passData.voxelBuffer, 1, AccessFlags.ReadWrite);

            if (passData.rendererList.IsValid()) builder.SetRenderFunc((PassData data, RasterGraphContext context) => ExecutePass(data, context)); ;
        }```

why does this

(raster render pass)

throw InvalidOperationException: Trying to use a texture (Voxel Buffer) that was already released or not yet created. Make sure you declare it for reading in your pass or you don't read it before it's been written to at least once. UnityEngine.Rendering.RenderGraphModule.RenderGraphResourceRegistry.Check

I don't get it, I am creating the texture with CreateRenderGraphTexture

Then I'm doing the SetRandomAccessAttachment

What am I missing? Is this just bugged and is impossible to do SetRandomAccessAttachment?

I tried it with UseTexture too

Just in case

[lost basalt]

Well it seems like it works with a RenderGraph.ImportTexture type of RenderTexture

I guess this is a bug then

[signal fractal]

Does anyone have any idea why the normal vectors might be displayed when using a spectator camera? It's only visible on the screen, not in the VR Headset.

[pure zinc]

ohh okey thank you

[stoic cradle]

Does it fixes it if you do builder.SetRandomAccessAttachment(passData.voxelBuffer, 1, AccessFlags.Write); instead of ReadWrite access? Looks like the texture can't have the Read flag if it is just created

I've been a week trying to digest how this RenderGraph passes work, there is not enough clear documentation, it is really cool to do this thing, but there are so many classes and structures leftover that is a mess, there are like three or more texture hanlders types

And the explanations on the documentation could be improved by using less overhead of classes, for example Unity provides an object that is passed through from the moment the graph is created, to the renderer function that is executed in the moment the pass is made, but there is no real need to use this Data object, using contextual handlers would be much appreciated to know that there is no magic happening with this object passed

[marble vigil]

A workaround might be to render the whole UI onto a rendertexture and use it as an additive material
But it does limit the style of UI you can have

[pure zinc]

i made a shader for the UI and it works very well thank you for your help

[livid violet]

Hey, had a question about RenderGraph in Unity 6. I'm trying to write a base class for creating any number of render passes, where each feeds their final output texture to the next pass. I have the first pass working, it just blits a texture with a material. what I'm trying to figure out is how in subsequent passes I can read the previous pass texture. I know I can use ContextContainer.Get<T> . more info in docs here but that depends on a type and doesn't support duplicate instances (which I need to support). I could generate a bunch of global textures with unique names, but I'd like to avoid that for performance reasons. I've tried to use frame data, but none of it seems to contain data about the previous pass, I suppose because it's been cleared?

[lost basalt]

I ended up using a RenderTexture asset, at least I can see what's being written into it that way. Thanks for the tip tho! I will check if Write works

[lost basalt]

you could probably create a custom system for this, no? you can just store things in a static list and refer to the data with IDs or something like that

just make sure to call the UseTexture if needed so the render graph doesn't whine about it

or even better you could in your data object set the said list

or is that not allowed? multiple passes using the same data type?

and same data object

[marble vigil]

What kind of shader solution did you arrive to?

[livid violet]

interesting. not totally sure, but you've given me some good ideas I'll try. thanks

[urban sleet]

My build size is being largely bloated by URP and I don't need a vast majority of its assets

is there a way I can better manage them or is that just how the package is?

[marble vigil]

have you located which ones of those are from URP

[urban sleet]

it's a mixture of URP, test framework and input system

but a lot is URP

[iron compass]

You could just remove the feature they are used/referenced in.

[winged valve]

Is there a way to tell URP to not render anything on its own? I'm making a custom render feature which renders only specific objects in the game world with a specific shader pass, however URP wants to render 2D lights and other stuff which I have no need for that specific camera.

[willow sable]

Hey, I just added urp to my project. I changed all the materials to lit, changed urp assets in the settings etc etc

and yet for some reason my scene is still visible even without lights

(2D)

[sinful gorge]

Maybe use light layers or culling masks in a way?

[sinful gorge]

Could it be that there is a default ambient color?
Check the lighting settings and URP 2D lighting settinga

[winged valve]

Thanks for answering, I guess thats what I have to do but its a bit weird that theres not a way to control the render process better than that

[iron compass]

if you need actual control you are supposed to make your own custom render pipeline. That is the whole point of the system (so they can be lean and not overly complex by supporting every feature), URP and HDRP are "just" templates for specific purposes.

[winged valve]

Hm makes sense, however having to make an entire render pipeline just to toggle off a few features within the pipeline seems quite overkill

But since its not available I'm going to assume its just not easily doable without modifying the pipeline by a magnitude

[onyx lance]

I have a shader (shader graph) that adds a bit of warping to the scene. It works perfectly fine, but when I swap to Android platform, the shader just becomes grey. Any advice?

[marble vigil]

You specifically need to use the sprite lit material, and 2D lights if 2D lighting is what you want

[willow sable]

I use sprite lit everywhere

[marble vigil]

Lit sprites are full bright until 2D lights are added into the scene, once there's at least one light the sprites can show darkness

2D renderer has no "ambient" light, a global light 2D is the closest equivalent

[willow sable]

okay, i tried adding global light and it didnt work. Adding and removing spot light solved it

[sinful gorge]

How is the shader made?
For full screen shaders, do you use render pass 0 or 1?
Blit has issues, so use draw procedural

[wicked siren]

Ive copied over a shader i was using in unity 3d to 2d and now it doesnt wanna work and i think its something to do with my URP cause whenever i assign the shader material to the full screen pass renderer feature the whole screen goes black and i dont know why

[strange pier]

In case someone else discovers this message in the future with similar issues:

I was able to solve my problem by changing the default graphics API for Windows from DX11 to Vulkan.

After the switch, players who were getting consistent GPU driver crashes in builds after playing for 10-30 minutes have reported no issues.

I still have absolutely no idea what the problem was... so it's a bit of an uneasy feeling, but I'll gladly take the workaround as a win. 😅

Helpful tags for future comment searchers:

DX11 error, build only crash, Nvidia GPU driver issue, VRAM memory bug

[urban sleet]

I not sure where these things are being used. My project is so small and I've interacted with URP so little outside of camera settings that I don't know what these things are for

[vivid harness]

Are aovs or render passes possible in urp for compsoiting cineamtics?

[uneven path]

Hey I'm pretty new to renderer stuff, how do you use front and back face culling? Trying to do the thing in the image but I'm just kinda fumbling around with documentation and no real knowledge.

[haughty garnet]

Unity provides an option for face culling for their shaders, and if you were to use shader graph it's available through the panel for where you set the target pipeline.

[cloud night]

Hi, does someone know how to fix "Failed to Compile/Universal Render Pipeline/Lit"? Lit does not appear in Shader > Universal Render Pipeline. I'm also getting pink materials on those materials that use Universal Render Pipeline/Lit.

[little wharf]

Hey, basically the compiler failed to compile lit shader.

Solutions:

1. You might need to create a new project and import your files to it.
2. Use another shader.

[cloud night]

How can I fix this? It happens very often and I cannot afford to reimport a whole +50GB project to a new one. I mean, there must be a fix?

[little wharf]

Then you can reimport those shader's

[cloud night]

How?

[little wharf]

I am actually not free today. Thats kinda a big thing to write can you dm me?

If you have no idea about the topic, please don't "try" to help.

[little wharf]

bruh, it was 2am here and i needed to sleep badly. And you are talking these.

[soft quest]

hi, everyone. Nice to meet you, can you help me?

[little wharf]

1. Cut the lit shader from your project and then past it back.
   If this doesnt work then:

2. Set your shader varient to 500 or some in project settings and player settings then import the production ready shader from shader graph in package manager (samples). Then navigate to lit shader graph. Thats the shader youll use. Or you can also change that in to shader code.

[little wharf]

What help do you need?

[soft quest]

thank you for your replay.

nope, I'll send you screen.

[little wharf]

That might be for material that the tree is using, change it that might fix it.

I can see where is the problem

change those materials properties

[noble moat]

If anyone knows off the top, does URP use Per Pixel at this point, or Per Vertex? I assume per pixel

"while currently the LWRP, URP, and Shader Graph shaders all use per vertex, the HDRP’s built-in shaders use per pixel. In a future update to Shader Graph (7.2.0) it should be switching to per pixel, and URP’s built-in shaders sometime after that" this is from an older article

[noble moat]

this is from this article: https://bgolus.medium.com/generating-perfect-normal-maps-for-unity-f929e673fc57

[soft lion]

Per Pixel what? Lighting?

[cloud night]

As far as I know, if you are talking about lighting, you can select between Per Vertex or Per Pixel for additional lights in your URP settings.

[half storm]

In a custom render pass, can I somehow replace the material of objects in the opaque queue with a transparent material?

I redraw the objects of a certain layer when they're occluded. I want it to be a blend of the color of the occluding object and black. I want to ditch the opaque texture if I can, so the idea was to give it a dark-semi transparent material

Currently it seems that attempting to give a transparent material override to a render pass in the opaque queue will render the objects as unlit white

[noble moat]

cool deal, thanks

[noble moat]

it has to do with the Normals calculations, so i linked the whole article, otherwise i'd just be repeating the whole thing 🙂

[oblique briar]

Do you suggest doing an additional material pass to render a decal of blood on a skineed mesh for a monster?

I mean, additional material on the same surface

[lost basalt]

don't do it in the opaque queue

theres no reason why you couldn't just render them beforetransparents or aftertransparents

however

[lost basalt]

what you are saying here is

you want to draw objects that are occluded

well

good luck with that, because afaik you can't query something like that from the culling api

reverse culling that is

[rare fossil]

How do I go from Universal RP 14 to 16? When I look in the Package Manager there is no option to change versions

[dry willow]

They are tied to Unity versions. URP 16 would be 2023.2+

[maiden depot]

Is there a way to make decals work with transparent objects?

[iron compass]

Not with built in decals

[maiden depot]

you mean built-in RP?

[iron compass]

Not possible with the URP decals projector/shader

[maiden depot]

damn...

[rare fossil]

Thank you! I was going crazy trying to figure out what I was missing

[nova parrot]

Does anyone know how to order custom render passes in URP? There only an enum for "RenderPassEvent.AfterRenderingGbuffer" but it doesn't guarente exactly in whate order those run...

[dry willow]

The enums have values at various intervals, so you can add small offsets, e.g. RenderPassEvent.AfterRenderingGbuffer + 1 would definitely render after

[nova parrot]

Oooh I did notice they were at various interval but I thought this was just for future proofing, I'm glad it's actually ordered like that, thanks!

[rare fossil]

Whats the best way to apply a shader to a Canvas?

I'm trying to apply a shader to the entire UI.

[marble vigil]

"Best way" depends, as always
What kind of shader and what kind of UI

[rare fossil]

Just experimenting right now but for example a CRT shader on the entire UI.

[marble vigil]

Unity 6 has Canvas graphs for Shader Graph
Sometimes you might prefer to render the UI to a render texture and apply a shader to that and render that on screen

CRT shaders are usually fully full-screen, but it's possible to make them affect only the UI with the above technique

[rare fossil]

I'm still new to Unity, coming from Unreal so please excuse my lack of knowledge but:

I would need to

• Create a new camera
• Capture the UI to RenderTexture
• Apply the shader to the RenderTexture
• Have the new camera render that RenderTexture?

so I would need two cameras in all my scenes? (one for the game, one for the UI)

[marble vigil]

After step 3 you could display the RT texture as a full screen UI image on camera 1, or overlay it as a custom post process effect
Alternatively after step 2 could just place it on a quad in front of the camera that has a material with a CRT shader
Alternatively still, after step 2 you could look into "full screen blit" feature (or in Unity 6 the render graph API) for applying the shader and rendering the image

[rare fossil]

man I'm amazed it's this complicated to simply apply a shader to the UI as a whole.

It's like 2 clicks in literally every other engine

This is kind of enough to simply abandon the effect altogether

[marble vigil]

You be the judge of that
In Unity, UI is made of geometry, rather than an image so there's the extra steps of turning it into an image and then rendering it back

[rare fossil]

yup not worth it, atleast for my current project. Well thanks for the help!

[maiden depot]

Is there a way to make shader that ignores fog? I know that it is possible in built-in, but what about URP? A great addition would be if this is possible with shadergraph :3

[twilit acorn]

If you're working a shader manually, just don't include fog in the lighting calculation.
In shader graph, I'm not sure if it's possible, since unity would apply for as part of the lighting calculation. Maybe use an unlit shader graph.

Try it and see for yourself.🤷‍♂️

[maiden depot]

okay, thanks

[marble vigil]

https://discussions.unity.com/t/how-to-disable-fog-in-lit-material-shadergraph-urp/935842 This works

Assuming you're using Lit since you need it disabled
Unlit doesn't implement any fog

[maiden depot]

yeah, just what I need 👍

[fickle ravine]

i was following a brackeys tutorial to get the basics for URP but my sprites ar all bloby now

i got an error saying "Sprite Tiling might not appear correctly because the Sprite used is not generated with Full Rect. To fix this, change the Mesh Type in the Sprite's import setting to Full Rect
UnityEditor.EditorGUI/PopupCallbackInfo:SetEnumValueDelegate (object,string[],int)" but when i did that, the texture was the same except it was surrounded by a black box

[marble vigil]

this happens if you make a custom sprite shader but exclude the sprite alpha

[nocturne yarrow]

Could someone help with this strange error I've been dealing with for awhile?

The missing feature is ambient occlusion

and pressing the attempt fix button displays this message in the console:

thanks!

[marble vigil]

If you delete the missing feature and re-add SSAO, does it work then

[nocturne yarrow]

If you mean delete by removing the feature from the inspector and then adding it back, then no, otherwise I don't know how to delete it.

[marble vigil]

Sometimes making a new urp/renderer asset helps also

Because they might get corrupted in some weird way

[nocturne yarrow]

Hm okay i haven't tried that yet, I'll give it a go and let ya know, thanks.

[nocturne yarrow]

Didn't work showed the same error.

[oblique briar]

Why every time I update Unity I need to recompile 13,000 shader variants in URP for several hours? This is unbearable

In addition I can't really use the PC while Unity takes 100% of my CPU

[nocturne yarrow]

Well anybody got any ideas? sorry for asking again.

Wait never mind I finally found the solution to this issue, if you have both urp AND hdrp on the same project, when you add SSAO to the renderer it adds the hdrp SSAO? I believe that's what happened because after removing hdrp and re-adding SSAO the problem was fixed. Found the answer here: https://discussions.unity.com/t/i-get-an-error-when-i-try-to-add-ssao/933881

[digital wharf]

This happened to me before, and creating a shader asset variant seemed to help a lot

[radiant night]

Hey! Does someone know if unity is using cluster or tile deffered rendering ?

[cyan swallow]

Hi all, I can't seem to find an answer on the forums for this: Is there a way to create a RenderTexture from an RTHandle, where I can have a color and specify a bit depth for a depth buffer?

RTHandles can only be color or depth, but RenderTexture can be both. The reason I need to have a RenderTexture with a color and depth is because assigning a rendertexture output to a camera in URP will coerce the cameraTargetDescriptor to whatever depth the rendertexture has, so if I want to programmatically create a RenderTexture with support for render scale and reuse textures where appropriate (ie, RTHandle API) then I need the above

[hearty tundra]

@cyan swallow you could drop setting the target texture and set custom separate render targets and render objects you need from a custom renderer feature.

[queen cloak]

anyone using URP 17 have experience with passing texturehandles from one pass to another? I have a situation where

RenderPass A

• Creates a ContextItem where I can pass a TextureHandle

RenderPass B

• Attempts to retrieve's the frame ContextItem and sets a Read dependency onto the TextureHandle

The problem is that when RecordRenderGraph is executed, Pass B is initialized before Pass A. This makes it difficult to set the Read dependency onto the TextureHandle and RenderGraph will pretty much fail

[queen cloak]

Worth noting that RenderPassA and RenderPassB live in 2 different files associated with the ScriptableRendererFeature

[crystal forge]

Hi, if you have additional cameras rendering into rendertextures for VFX etc., would you typically setup specific renderer pipeline assets for these to disable anything you don't need?

[queen cloak]

wdym?

like disable objects you don't want to be affected by the vfx?

[crystal forge]

I mean general renderer settings. The camera has some settings of it's own, but also references the Renderer Asset, so presumably uses some of those values? (Quality settings, lighting, shadows). If you wanted to limit this for a rendertexture camera, I assume you might want a lower quality set renderer asset?

[queen cloak]

yea you can do that

[crystal forge]

is it the right way though?

[queen cloak]

i personally just do everything in 1 camera with renderer features

it really depends on what you're trying to achieve with a separate camera

since you're rendering to a render texture, in my head you can use a single camera, add the RenderObjectsPass and render it to the RenderTexture

then use the RenderTexture in w/e fashion you need

[crystal forge]

Yeah, but in that situation you're using that cameras setup too - position, orientation etc... I have some top-down orthographic cameras for rendering particles into a rendertexture for example.

[queen cloak]

your render feature can override the camera's projection

so you can render it from a diff pov

and just restore it back when you're done

not too familiar with using a separate camera approach atm, but your camera just default to a specific rendering asset

so i dont think it's an incorrect way either if you need lower fidelity

for an overhead ortho camera & render texture setup

[crystal forge]

ok, thanks

I remembered why I was asking now. I render a camera into a rendertexture, but I don't want it cleared each frame, so the effects accumulate. But the Renderer Asset had the Screen Space Ambient Occlusion render feature on it - and this was causing my RT to get cleared because this camera was using this asset. So I think I'll need one asset for the main game camera, and another for this RT camera that doesn't have have this SSAO render feature.

[queen cloak]

https://docs.unity3d.com/6000.0/Documentation/Manual/urp/render-graph-pass-textures-between-passes.html for reference im trying to do this but add explicit read/write dependencies on the textures 🤔

but kind of inverse, where Pass B needs Pass A's RenderTexture for read access, not write

[cyan swallow]

you can in 2023.3 / Unity 6, but not from 2022.3 and earlier (I need the full scene, not selective objects)

[cyan swallow]

This should be fine, what order are you enqueing them in? are they on different renderpassevents?

[queen cloak]

same render pass events, AfterTransparents.
they're in separate renderer feature objects, so I can't rlly control when enqueued gets called

[queen cloak]

i'll try out the same renderer feature

[queen cloak]

well i can see the example in the link working, I'm still getting an issue where

• RenderPass B: The Type <PassedContextData> has not been created yet.

• RenderPass A: Is pretty much the RenderObjectsPass, the main difference is that it creates 2 resources for depth and color attachment to write to. The additional color attachment It's writing to is what needs to be passed to RenderPass B.

All in the same scriptable renderer feature with RenderPassEvents being AfterTransparents

• RenderPass A enqueued first
• RenderPassB enqueued second

ah nvm, think i got it, had to recreate my renderer asset. Looks like a lot of legacy stuff in my upgrade interefered

[hearty tundra]

Wdym, pretty sure the API supported just getting a cull result list that includes all objects on the layers you specify and passing it to draw renderers API for literal years. It's what the premade Render Objects feature uses under the hood.

[prisma basin]

Hi, I updated from 2021.3 to Unity 6, but now I'm getting these errors. I made sure I have the latest URP and Core packages but I'm still getting the same issues. Anyone ran into this or know how to fix it?

[thick hinge]

when working with the Renderer2D in URP and writing a RenderFeature is there a way to insert a few custom draw renderers calls at a certain point in the 2d sorting?

[dark plover]

Why is my camera doing this? Been trying all sorts of different things but can't figure out what is happening.
This happens when I turn on TAA, but if I turn it off, the edges of my hexagons are broken at some zoom angles / camera positions

This is with No Anti-aliasing, but MSAA turned on under Output

[marble vigil]

First thing change game window zoom from 1.1 to 1

It's now scaled up to 110% which will cause distortions

[dark plover]

looks slightly better with no anti-aliasing & MSSA but same issue with TAA

[lucid lantern]

When do we need to use commandBuffer.SetGlobalTexture and material.SetTexture? I know the first one will set it globally and the second one will set it local to that material. So my question is; can we use the global thing in any scenario or what are the drawbacks?

[thick hinge]

well do you want it to be global or per material

[lucid lantern]

Well what are the drawbacks of using global? Maybe let me give more context. I have a feature that contains 1 pass and in that pass’ Execute function, i am calling different shaders in order (2 CS and 4 FS). I am trying to understand if it is possible to use my pass for multiple instances(multiple cameras) without any problem? Recently i read that unity will execute different cameras in different passes. But still, do i need them to be global or per material? Or this should not be an issue for multiple instances?

[ebon karma]

TAA is TEMPORAL Anti-Aliasing. It jitters your camera and then smoothing frames to get rid of Aliasing

[dark plover]

that's nice to know, but doesn't really help me fix my issue

[obsidian basalt]

The command buffer will be executed later, not at the same timing material.SetTexture executed. So if you need to set different textures for each camera pass, commandBuffer.SetGlobalTexture is needed. CS has commandBuffer.SetComputeTextureParam for this, but FS doesn’t.

[lucid lantern]

You said: if you need to set different textures for each camera pass, cmd.SetGlobalBuffer is needed?
Why?

FS doesn’t have, what is the alternative?

What is the difference between Shader.SetGlobalTexture and cmd.SetGlobalTexture?

[obsidian basalt]

In SRP.Render, Shader.SetGlobalTexture runs immediately on main thread, cmd.SetGlobalTexture will be executed on render thread with other rendering command. So if you want to do something like 1.Set textureA, 2.Draw with a FS, 3.Set textureB, 4.Draw with a FS, you need cmd.SetGlobalTexture to submit the correct sequence for render thread. There is no alternative command to set the local texture of a material, with commandBuffer.

[lucid lantern]

Thanks @obsidian basalt for that! So running in global texture would be totally fine in my case because i have multiple shaders? And we need to execute them in order so we need the commandBuffer? And also, the Render will create unique instance of the shader so there is no conflicts between multiple instances? Am I correct?

[obsidian basalt]

Using global texture with commandBuffer is fine for the case.
The Render doesn’t create unique material(shader) instance for each camera, but there is no conflicts. The draw call with a shader that samples global texture uses current set global texture. You can use one material instance to draw multi times with global textures, multi cameras.

[cyan swallow]

sorry, to clarify - yes, you can schedule an extra pass via render features, but I am referring to redirecting the built in opaque, transparent and skybox passes to output them to a separate texture. I don't want to schedule an additional draw via render textures, because this duplicates the draw calls of opaque/transparent/skybox

The only reliable way to do that pre-Unity 6/2023.3 is to either get these passes and set attachments via reflection, or configure the camera to output to a texture. But the texture output can cause errors if the render texture doesnt have a depth buffer (eg because it represents an underlying RTHandle)

or well, other way really - because it was created from the RTHandle API and then you've called handle.rt

[hearty tundra]

But if you've got a separate camera rendering to a render texture, you're invoking the whole render pipeline as well @cyan swallow

[cyan swallow]

aye, which is suboptimal

[hearty tundra]

If you want to just copy existing color and depth, what's stopping you from copying them from the camera descriptors from a pass that's injected right before post processing(or after if that's what you need)?

[cyan swallow]

basically its for pixelated camera rendering, I support both methods at the moment - redirection of the Opaque/transparent/skybox to a render texture ('virtual' subcamera) or an actual physics second camera. The reason for needing to support both is because even if you do virtual redirection, things like decals or other screenspace effects can have issues - so its a balance between compatibility when users need it, or raw performance

ehhh long story short, you don't want to copy existing color and depth - you actually need to render the scene using different camera view and projection matrices to properly capture sub-pixel motion without creep

so there's a lot of other stuff going on, but the very particular issue at the moment is about trying to get a RTHandle with a depth buffer so you don't trigger errors in URP

(see: https://discussions.unity.com/t/bug-rendertexture-create-failed-colorformat-depthstencilformat-cannot-both-be-none-when-dbuffer-decals-and-camera-output-to-texture-fix/1521868 )

[hearty tundra]

You could drop the rthandle support and use rts directly then, the likelihood of a pixelated game enabling URP's builtin resolution scaling is zero.

There is a way to go in a reverse way, you can create rthandles from rts you create yourself. I think it's somewhere in the rthandle manager API.

[cyan swallow]

actually, I support renderscale while maintaining the world-space pixel size and using a pixel art AA filter - its useful for mobile

[cyan swallow]

problem is the above - I really want the render scale support, doesnt seem worth dropping it for this one feature on 2022.3 (when people will b emoving to unity 6 soon anyway I guess)

people were more hesitant about moving to unity 6 when the runtime fee was there, but I expect more will migrate now

[hearty tundra]

It's gonna be raw and buggy for years just like every other Unity release 😆

[cyan swallow]

😛

renderPipelines.unify()

render graphs is a solid upgrade though, much as we grumbled about rewrite work its a good change

[hearty tundra]

I really doubt that making yet another pipeline is something other than long term wishful thinking for the next couple of years especially after the exodus of graphics devs from Unity.

[cyan swallow]

yes, telling that there were no concrete slides for it at unite

[iron compass]

its not gonna be a 3rd pipeline, they made that very clear in the roadmap talk

[cyan swallow]

I guess the fear is of incompatibility between prev URP/HDRP and whatever comes next though

[iron compass]

the whole idea is that there is no incompatibility

its all about authoring once, deploy anywhere, and to do that (apparently) they aim to make all pipelines use the same units and shader model

[cyan swallow]

yes, but because they don't at the moment that means breaking all currently existing custom shaders and passes

[iron compass]

on top of that they can then still use the implementations of URP/HDRP they have now, but the parts you as the dev care about are unified

[cyan swallow]

to be clear, I do think its good for unity in the long run, I'm just worried about having to rewrite all shader passes again so soon after the rendergraph change

[iron compass]

there has been a long standing recommendation to not make custom shaders outside shader graph for that very reason

and because shader graph is so limited, there will be shader graph 2

[cyan swallow]

yes, but shader graph still does not support custom passes

so you are not able to follow that constraint the second you need a custom pass

[iron compass]

U7 (or whatever its called) will have block shaders

[cyan swallow]

also, there's a difference between shaders (shadergraph) and the render pass code

yes, and block shaders will require recreating all custom effects/shaders again

(done outside of SG)

[iron compass]

you are free to continue using the old APIs

[cyan swallow]

even though it has been clear for a few years at least that shaders must be in SG (whether you can stay within that constraint is your own risk), one of the strengths from day 0 of the SRPs has been the ability to make custom render passes and pipelines

[iron compass]

well, thats only a meaningful strength to large teams that can maintain that kind of thing

[cyan swallow]

only for projects where you control that - as an asset creator I have to support everything

[iron compass]

it was a very hollow feature in any practical sense

[cyan swallow]

there are a great number of assets that use it

and I think one of the strengths of unity has been in having an asset store to spread out some of the workload and allow some reuse of these things - obviously I have biases though 😄

[iron compass]

well, idk why you're complaining, the new system would simplify it for asset creators

if you've invested into solving unity's shortcomings and they are fixing them now, you can't really fault them

[cyan swallow]

in future, yes, but in the meantime I've had to rewrite my assets twice in past 18 months

[iron compass]

also this is still at least 2+ years in the future

[cyan swallow]

I know, to be clear I am not begruding them the change, unification will be good in the long term - but what I do begrudge is the head in the sand 'it will be painless' message that keeps being said. It wont be, it's going to suck hard for anyone who is using these features beyond more than just the superficial editor level atm

and of course, you go below the hood at your own risk, I know that

[iron compass]

i think no sane markeing person will go on stage and sell you on painful changes

[cyan swallow]

haha, very true

but it sucks literally finalising the rendergraph API changes this week to be told to do it all again in a short while

hopefully not too short as you say though!

[iron compass]

well, rapid changes also means you can sell more

(unless you are an altruistic seller that does generational updates for free)

[hearty tundra]

Small teams need stylized lighting and effects as well, that's kinda a common feature in indie projects 👀

[iron compass]

yes, but you can't realistically make a custom SRP or maintain complex custom passes as an idie team

[cyan swallow]

yes this is unfortunately me 😄

5 years, no upgrade cost

[iron compass]

these stylized graphics should ideally be possible, to a large extent, with the available, integrated pipelines

[cyan swallow]

I think you can if you use assets, and I think unity does pitch itself somewhat as a small team/indie friendly engine where you can purchase the bits you cant make yourself

[hearty tundra]

Huh? Then what am I doing maintaining a bunch of custom rendering shenanigans on top of HDRP as the only tech artist on a team 🤔

[iron compass]

you can go pretty far with assets in URP, even beyond HDRP in many way except lighting... but thats not the same as making a truly efficien t custom thing for your project

[cyan swallow]

agreed, but for most indie games I think efficiency is over-egged and they will get by with a substandard solution if it lets them get the visual style they want

[iron compass]

idk, sounds like questionable scoping, but maybe not.

[cyan swallow]

I feel this is somewhat of a 'no true scotsman' argument though

[iron compass]

i mean how much value does your project get from those custom things? is your project selling because of them or are they gratuitous?

[cyan swallow]

that's not for me to say, that's for the people using the asset store to decide

I gather unity does well off the asset store, so clearly it has some traffic or value for enough users

[iron compass]

that was in response to bea

[hearty tundra]

Kinda need to keep pushing things forward when you're selling a sim.

[iron compass]

there is no clear definition of what indie is, so it will always be a scotsman argument.

[cyan swallow]

back to the original points, I do agree it's going to be better in the long run when there's more compatibility. And there's plenty of changes to be excited about. I'm just also expecting a bit more pain in the meantime

[iron compass]

depends on the sim, supermarket simulator begs to differ 😉

[wanton harness]

Can anyone explain why URP cannot exclude camera velocity from the Motion Vectors for motion blur?

Is it possible to work around this? Like storing the camera's velocity myself then subtracting it later.

[ivory ocean]

Hi, is there any way to make only parts of my scene darker? I have the overworld and a dungeon in the same scene - the problem is I need to change the lighting depending on the environment you are in - but I cannot just disable the directional light, because my game utilized ingame cameras, so disabling the direcitonal light, would also influence the lighting on the overworld, which is not what I want

[digital wharf]

Create two seperate directional lights and choose what layers they should affect

[slate grail]

Is there a way to only render some layer. I want the hidden render to not render behind the player object but others like walls

[rich sierra]

If I want a line renderer to have a 9-sliced material (so it behaves like a sprite) do I have to create my own shader in shader graph? So far none of the materials in the URP-category seem to do the job. They all tile the whole texture.

[mighty cargo]

Struggling on this but I'm trying to get better shadowing in my character's mouth cavity. Even when the mouth is fully closed I can't seem to get it fully shadowed.

I've set Shadow Resolution to 4k, lowered Max Distance to as low as 5m as well as messing with the Depth and Normal Bias. Is there anything else I can do?

I've also tried setting my mesh's shadow casting to Two Sided.

[marble vigil]

So what does the problem look like

[mighty cargo]

All good, I managed to figure it out. I had another asset messing with the shadows and confusing things.

[stray scroll]

is it ok to move the settings urp folder to a different folder in the unity project? (Instead of sitting at /assets).

it seems like all the editor settings reference it so it should be fine, unless anything is getting these using path...

[marble vigil]

Since they are assets I expect they have to be under /assets/
But you can have any sub path under that

[queen cloak]

hmm in a render graph architecture, how can I ensure that a renderer feature can be reused multiple times?

E.g if i have:

• Renderer Feature A write to a TextureHandle
• Renderer Feature B read from said TextureHandle
• Renderer Featurer A1 - which is the same as A, write to the same TextureHandle, but must occur after Renderer Feature B?

InvalidOperationException: Trying to use a texture (_ColorTargetTextureHandle) that was already released or not yet created. Make sure you declare it for reading in your pass or you don't read it before it's been written to at least once.

I get this issue because _ColorTargetTextureHandle is released/not created which comes from Renderer Feature B.

If I remove Renderer Feature A1, everything works as normal 🤔

was hoping to reuse the same resource but if i have to create a new resource 🤔

[hazy trail]

I have an URP question... Why is my Unlit all white instead of textured properly?

I want to go 100% unlit and just static meshes, because I plan on having 500,000 space ships with collision not counting lasers... I've done this before with HDRP at 200,000

I want my URP as literal basic as possible for the fastest rendering possible... I've done 3 million non collision entities before, not optimized... I want to go as optimized as possible in URP

So unlit should be faster than lit... but I'd assume it'd have some sort of global illumination to get it at a solid texture... I've been trying to change from HDRP to URL since Aug 1, so it's been about 200 hours and 2 months work on this engine transfer from HDRP to URP... So I'm low key desperate for help to get the texture/coloration working on UNLIt. Thank you

[hushed dirge]

It's all white because it's unlit... the shading comes from the lighting

[violet bison]

are you using the default Unlit in URP or did you make one yourself?

nevermind, I can see you're using the default.

Using the same shader and just applying a texture to the material was all I needed to get this to work.
I can see your base map is empty in this image though. How are you planning to shade the ship?

@hazy trail Looking at your HDRP-screenshot on top I don't see anything in the base-map there either, so I don't really know what's shading your ship. It could be like redwyre said, and the normal-data is what's shading the ship.
Normals of course need light to do anything useful.

[timber pagoda]

Is there any way of changing the keybinds of the urp DebugManager without cloning the package? Having it be ctrl+backspace is the worst choice ever, lol

[marble vigil]

I'd assume not
What's so bad about that particular combination?

[timber pagoda]

A lot of games have text input, and ctrl+backspace is the standard "Delete previous word" key combo

[marble vigil]

That is a useful one, but ultimately just a convenience
I think other quick text editing methods still work? Like ctrl + delete and ctrl + arrow keys as well as ctrl + shift + arrow keys followed by backspace?

[timber pagoda]

yeah, but habits are hard to break, lol

[lucid lantern]

All what you said is wrong.. 😑

[hazy trail]

Is there a way to have 0 lighting. No lighting at all, and everything globally illuminated at a static scalar ? This would save on processing speed.

[hushed dirge]

you could bake some shading into a texture but it's going to look weird

are you actually GPU limited?

[hazy trail]

I'm pushing the absolute envelope on MAXIMUM objects rendered in DOTS/ECS... I think I can get 5-10 million at 30 FPS, this is when I wasn't doing it well; https://www.youtube.com/watch?v=Ws-7rqluv6w

[hushed dirge]

If you don't know what is the limiting factor for performance is then you're just guessing what is going to be fast and potentially wasting effort

[hazy trail]

Chat GPT says I'm aiming for the "absolute minimum rendering cost", no shaders, no reflections, even a custom shader that's better than unlit is possible. This type of demo videos makes Unity look good to the public

[hazy trail]

I know one limiter: The Graphics rendering package. When I went to HDRP, my FPS dropped by 8x, and only with finangling could I get it down to only drop 2.5x

[hushed dirge]

but do you know why?

[marble vigil]

chat gpt doesn't and cannot know what the limiting factor of your performance is

[hazy trail]

I think with URP, I can get it below 1x my initial, which could lead to 1.5 million things rendered at 30 fps, (in a playable game)

I know the limiter, the rendering.

I was asking a different question; How do I display an Unlit object yet still show the texture and color... I see many people on youtube using Unlit like this

I believe there's an ambient lighting setting

[marble vigil]

Unlit does that, but you don't have a color texture as mentioned earlier

[hazy trail]

Is this true? In the Lighting Settings panel, under Environment Lighting, you can control the ambient light level.

[hushed dirge]

"rendering" covers a dozen different factors

[hazy trail]

Correct redwyre, I'm focusing on my unlit texture rendering like the lit version of it

The top is lit, button is unlit in URP

[hushed dirge]

I have told you why, there is no light, therefore no shading

[hazy trail]

So I need ambient light

[hushed dirge]

it will always be one solid colour

[hazy trail]

Not true

I see on youtube people having textures n stuff

[hushed dirge]

if you add a texture, sure

but ambient isn't going to change anything

[hazy trail]

Red, I believe there's a texture on that graphic, can you review the top correctly rendered lit version?

[marble vigil]

This may take a while so you'll need a thread

[hazy trail]

Thank you Spazi & Redwyre. Back to coding... Tech is tough... You know how to tell time in elementary school digital and analog(This is like knowing coding), but you buy a foreign car and you can't set the clock (This is tech). Knowing how to code isn't the same as knowing someone's tech. I appreciate you guys highly.

A game developer's time must be managed between ramming your head against the wall (techs) and getting stuff productive(using the techs you know). It's like intelligence (knowing stuff), and wisdom(using the stuff you know). It's like gathering ingredients vs using ingredients to cook.

[violet bison]

@hazy trail This is an answer to it no? You need a texture.

[twin yacht]

hello i want to learn to make VFX for mobile games , i have some general knowledge in 3D softwares like blender & houdini, just getting into unity

what is the standart workflow of making VFX mobile games

correct me if im wrong but as i understand the visual effects nodes work only in HDRP?

[soft lion]

Works in URP too but just not on mobile devices. Therefore the good old particle system is your best bet when creating visual effects for mobile devices

[twin yacht]

I see, u have any suggested in depth tutorial about that?

[soft lion]

I don't. Any particle system tutorial should do

[sinful gorge]

If you use vulkan pretty much all VFX Graph features work on mobile as well. Just OpenGLES is not supported.

I have used it in production without any issues.

( @twin yacht )

Since mobile devices often are GPU limited, I do recommend to use regular particles or shader based effects whereever possible for best compatibility and performance

But if something only works in VFX graph, that might be interesting

[soft lion]

Not long ago I saw a post by some unity staff telling that even high end mobile support is likely not happening in near future due to very inconsistent feature support by mobile devices, I think it was about ComputeBuffer support

@sinful gorge This one: https://discussions.unity.com/t/what-will-be-added-to-high-end-mobiles-for-vfx-graph/918745. Commented on june 2023 so very recently. It might work fine in some cases but there doesn't seem to be any guarantees about it working on even some high end devices

Don't really know what kind of difference the graphics library/interface will make but I assume some device manufacturer have created better support for some graphics features for some interfaces on their drivers

[sinful gorge]

Yeah it is not 100% supported, in the sense they cannot guarantee support and test it internally.
But the hard requirements are compute shader support, which Vulkan definitely has. If a device does not support Vulkan, the play store should not list it.

Personally work a lot with Meta Quest and other VR headsets, so the internal hardware will be the same. So that is easy to test once and then know it works for consumers as well

[soft lion]

Might we worth trying if something essential just isn't possible with the good old particle system but on most cases the particle system is a safe bet

[sinful gorge]

Yeah definitely

[brisk dawn]

Am i dumb or should this be rendering? Cause its not, no sprite appears.

Nvm, i figured it out

Nvm it doesnt work

It works when i manually add it, but for some reason when its instantiated in it doesnt? tf?

[winter oxide]

sorting layer maybe?

[marble vigil]

I would check the position where it's instantiated
Z position that's too high or too low can make it appear behind the camera, or behind other sprites

[hazy trail]

How do you set up your settings to be like 1996 PS1: No lighting, no shadows, no reflections, no fog. Just Texture and colors?

[oblique pier]

Use Unlit shaders. About the fog - not sure how it is disabled in URP

Although, didnt a lot of games back then use fog to hide low render distances? 🤔

[uneven path]

Help how do I turn this into a urp shader

I switched to urp and now everything is purple

[vivid harness]

HELLLLLP

Been trying to use sequencer but now

anytime i try to creat e asequence

it breaks and saves gameobjec tnot found

[vivid harness]

this happens for any unity project i open

[brisk dawn]

They are both at the exact same spot

[brisk dawn]

Oh, and I did solve the not rendering issue - Now the issue is, even though the two sprites are the exact same resolution, and exact same scale, one is way larger than the other

[marble vigil]

How did you solve the rendering issue?

[brisk dawn]

Turned out I was an idiot and the y scale was set to 0... yeah, not my brightest moment

[brisk dawn]

But now, the issue is this: The white and green sprite are both 256x256. They are both scaled the same, y and x are both the same. They are both positioned the same. But yet, one is larger than the other.

[marble vigil]

They likely have different PPU values in the texture import settings

[brisk dawn]

How do I change that?

[marble vigil]

in the texture import settings

[brisk dawn]

Alright, thanks, I'll try that

[humble ember]

Is there any easy way to get the Maximum Shadow Distance in URP?

In built-in I can do QualitySettings.shadowDistance

But in URP im getting a random value

[marble vigil]

How random exactly
And how are you getting it currently

[humble ember]

It's 40, not sure why

[humble ember]

And getting it with the single line
QualitySettings.shadowDistance

[humble ember]

i cannot belive that I cant get the active rendering shadow distance

Like, i need to make a specific script for each render pipeline to just get that value???

[oblique pier]

RP-specific code is normal

Unavoidable in some cases

[fast edge]

why are the textures so squashed?!!?!?

i made them using a software called blockbench btw

[oblique pier]

Wdym squashed? If you want sharp pixels, set Filter mode to None in the texture import settings

[fast edge]

alr alr i'll try later thanks for the advice

[vivid harness]

Hey does anyone have an issue wehre seqeunces won't create anything after creating th emaster sequence

its seems to have broken and is not working even after i ninstall and reinstall it

going a bit insane

[ornate tusk]

I think I posted this in the wrong chat, does anyone think they can help me with it here?

[sharp shell]

Im making a game where players can build maps at runtine and then play on those maps in the shooter mode, im using URP since its gonna be stylized.
My problem is that i obviously cant bake lights for something that doesnt exist and that the players will create, so i cant use mixed / baked lights, only leaves realtime lighting.
But realtime lighting looks very bad indoors / shadows look way too harsh, its like almost black indoors.
Is there a way to get light bounces or better environment light for realtime lighting in URP so that it looks better ?
Please reply-ping with an answer so that i can actually see it (incase i go to bed before someone answers)

[zenith prairie]

idk how to explain it

but when i move my camera

the decal like

flickers

and dissapears

[zenith prairie]

set texture filter mode to Point (no filter) and compression to none

[oblique pier]

That is called Z-fighting

You could spawn the decal a tiny bit outwards from the hit point

[zenith prairie]

ok thanks

[soft lion]

Are you using the decal system or flat quads?

[zenith prairie]

decal

[soft lion]

I don't think decals should suffer from z-fighting assuming the wall is within the decal bounds

[oblique pier]

They do, at least in HDRP, when the bounds edge is exactly on the wall

That being said, @zenith prairie could also just adjust the pivot of the decal bounds instead of moving it out

[soft lion]

That's what I meant by "wall within decal bounds". Edges tend to cause edge cases in general

[wise minnow]

helo, im stuck on urp 12. any ideas on how to update to urp 14

[open pasture]

Heyo!

I’m trying to render the world position of a vertex displaced plane into a texture, in order to achieve this I want to use a render feature that renders a particular mesh with an override material without having to use a second camera. To do this I’ve made a custom Render Objects (experimental) render feature that allows me to set a render target, other than that it’s functionally the same.

The issue I have is that the vertex displacement doesn’t seem to apply before it renders to the target texture. If I render it normally and then use a grab pass render feature to blit the cameras render texture it works as expected, but naturally also renders the result to the scene which I don’t want. If I set the depth write to disabled on the regular render objects it also doesn’t displace the vertices before the blit, but changing that in my own custom render feature doesn’t seem to do anything.

Unity 2023.2

[hazy trail]

I was told:

just remove the lightsources
and up the ambient brightness

For PS1 1997 rendering with no light

[fickle herald]

hello, 'Post-Processing' option isn't appearing, I just recently installed the URP, do I need to restart or something?
edit: checked the pinned messages, issue solved.

[sinful gorge]

Use Unity 2022.3+

If you already are, edit the manifest manually

[wise minnow]

Thank you

[verbal forge]

has anyone work with depth texture before? is it possible to get/create depth texture with some filters? (e.g. i only want to render depth texture for objects in layer "depth")

the code i'm working on for more context

public override void Execute(ScriptableRenderContext context, ref RenderingData renderingData)
{
    CommandBuffer cmd = CommandBufferPool.Get(nameof(OutlineRendererFeature));
    RTHandle cameraTargetHandle = renderingData.cameraData.renderer.cameraColorTargetHandle;

    // Clear Interactable RenderTexture
    cmd.SetRenderTarget(interactableRTHandle);
    cmd.ClearRenderTarget(true, true, Color.clear);

    // Draw Desired Objects to Interactable RenderTexture
    foreach (var inst in renderers)
    {
        if (inst == null) continue;
        cmd.DrawRenderer(inst, inst.sharedMaterial);
        Debug.Log("Drawing renderer" + inst.name);
    }

    renderers.Clear();

    // THE PROBLEM:
    // Instead of Blitting the Interactable RenderTexture, it should be "THE Depth" of Interactable RenderTexture
    cmd.Blit(interactableRTHandle, cameraTargetHandle, outlineMaterial, 1);

    context.ExecuteCommandBuffer(cmd);
    CommandBufferPool.Release(cmd);
}

[fleet orchid]

so I put a little 2nd camera rendertexture into my game I'm making, and just noticed that I have a whole other DoRenderLoop thing going on, which when I delete the minimap rendertexture (it's a 6464 res no lighting single culled layer) goes away again... makes sense, I guess.... but this 6464 is adding an entire ms, very almost the same as my entire full game render screen covered in shaders, far higher res etc. Is this expecte behaviour? Can you just not even use a tiny rendertexture? Is there anything I can do to get around this?

[opal plover]

I've got a material/shader that I apply to units in a custom layer by adding the material in the AfterRenderingOpaques event. Works great - but I'd like the shader to have a custom value per unit. Currently they all share the same value in the material.

How can I do this? Do I need to just add the material (manually) to all objects and change the value of the copy (via script)?

[ruby marsh]

hey, I would like to have some text/stickers on this fire extinguisher of mine
I know stickers can be achieved by simply using decals, but I have no idea how to make sort of "decal text"

e.g. use TextMeshPro as decals

[fleet orchid]

I wound up doing this in a command buffer instead of a camera and it seems to have gone from 1ms to 0.1ms

[oblique pier]

Does this help? https://docs.unity3d.com/ScriptReference/MaterialPropertyBlock.html
The other option is to instantiate thet materials, yeah.

[queen bronze]

do you want something dynamic or could it be baked into the texture?

just using decals for an object that always has the same text is not a good idea

[ruby marsh]

best one could be dynamic, but I'll do with baking

[queen bronze]

then create an image with text in your image editor of choice and UV map it using blender / maya. For such a simple shape UV mapping should be fairly trivial and a good learning task

[ruby marsh]

ah, okay, I overcomplicated again

[ruby marsh]

why?

do they produce a lot of overhead? haven't used them yet

[queen bronze]

depending on your usecase it would be totally fine but especially if you want your object to move or have many instances its not a good idea to use decals

and just UV map it would be the standard way

[ruby marsh]

okay, thanks for the info!

[opal plover]

Hm, that's how I normally set my properties on a local or shared material.. I didn't know it could be used on the URP pipeline materials.. It does say "it will result in a drop in performance" and I've already got an issue with that (likely low hanging fruit to fix but I haven't bothered yet.. I actually think it might be my implementation of pathfinding but all things in due time). I will probably just do the local material approach since I'm a dinosaur and like having things under my control a bit, given two options

[deep skiff]

Does anyone have the source for the built in "Render Objects" render feature?

I've got it mostly working for my needs but I need to tweak it slightly and would like to avoid rewriting the whole thing if possible

[dry willow]

Should be able to find it under the URP package (under RendererFeatures and Passes folders), though it might use some internal-only code so unsure if you can just copy it

[deep skiff]

Thanks, will check there!

Yep looks like this has it all, thanks.

[vale jacinth]

I’m looking to use Unity for Apple macOS GameDev, and was wondering how I could I introduce native macOS MeshShader into the URP?

[past thunder]

anyone here

that knows about the renderer

and the render features

[modern oracle]

converted everything in my project form brp to urp and most things went invisible, help!

the objects are still there just the textures are gone

the textures are still applied to the object and in the file explorer just not showing up in the scene at all

[light slate]

does URP dynamic resolution (ScalableBufferManager.ResizeBuffers(...)) support upscaling filters? i have FSR selected in my render pipeline and it works with the "render scale" setting there, but if i set render scale to 1.0 and use ScalableBufferManager.ResizeBuffers instead i get nearest-neighbor filtering instead of FSR

[sinful gorge]

Did you run the SRP upgrader already?
Is the terrain material working on URP and is it assigned in the terrain tabs?

[gilded mantle]

Hello everyone. I've been trying to apply some post effects to UI, but i can't seem to find any good way to make it. Works "fine" in built-in render, but in URP stacked camera affects base camera with post-fx for some reason. Changing stack order results in world obstructing UI. Any suggestions?

[gilded mantle]

...i was trying to make UI look like old terminal, maybe there's much easier way around idk...
bloom and lens distortion looked easy to make

[indigo knoll]

looks nice

[marble vigil]

This is likely a render texture on a curved mesh
Much simpler and looks better than a fisheye shader

[marble vigil]

In URP camera stacking, each camera's post processing affects all the ones below as the whole rendered image at that point in time is post-processed

Unity 6's Alpha Processing feature would be required to mask post processing out from layers below

[wraith wind]

So I got an odd problem I ran into. So I'm trying to use a texture to make an object only be visible in a 3D space. I use a circle and I end up with a lopsided square.
To achieve the effect I made 3 rotations of the texture and clamp them to each other.

Any ideas on how to make it a sphere?

[modern oracle]

I converted my brp project to urp and only objects that were in prefabs are visible, help

[coarse tangle]

Why is it that adding screen space shadows to my URP profile doesn't seem to actually activate them?

two screenshots, one with screen-space shadows disabled, the other with them enabled. the result is the same.
i've also tried forward+, and deferred modes, but all looked exactly the same.

(the colors on the building scroll)

[ebon karma]

I don't think S-S Shadow are even do something in URP

[fierce anvil]

Render texture is not working on the URP WebGL build, there is only a black part at the bottom-left corner showing instead of the camera render, In editor Render texture is working just fine. how do fix this issue on Webgl?

[patent stone]

Pretty sure that this is the right channel for this.
Why does my gameObject look like this in the scene view? i recently upgraded a urp so that i could do emission

[marble vigil]

Why does it look like what
Any more details at all?

[drowsy hinge]

This is probably a dumb question, but in the Unity 6 Preview URP, how can I simply just render a basic unlit shader to the camera?

[marble vigil]

What do you mean by "to the camera"?

[drowsy hinge]

so i have an unlit shader i made and i want it to be on the camera, if that makes sense. Im very new to shaders, so i am unsure how to do this. Previously in built-in, i would just just use OnRenderImage along with a Graphics.Blit to do this. However, i have since switched to using URP and have also switched to using U6 preview. I think i need to do somehting like a "render feature", but i have no clue how to do this.

[marble vigil]

https://docs.unity3d.com/6000.0/Documentation/Manual/urp/post-processing/post-processing-custom-effect-low-code.html

[drowsy hinge]

This method appears to only work with ShaderGraph, however the shader i want to use is written in ShaderLab. Is there a way to do this in ShaderLab, or do i need to re-write my shader in ShaderGraph?

[marble vigil]

Technically possible but it's quite a bit harder to write urp shaders than to make them in SG

[drowsy hinge]

aw ok, thanks for the help. Ill just re-write my shader in SG

[marble vigil]

Custom functions in SG are a good middle ground

[coarse tangle]

that seems to be my impression, although the docs say otherwise.

[marble vigil]

I don't see much any shadows in your screenshot, let alone screenspace ones
They are meant to supplement realtime shadows

[coarse tangle]

they're highly aliased in this pic, and missing entirely from the smaller detail.

i should've taken a shot with shadows turned off for full reference

but the roof is untextured. whatever detail you see on it is from the shadows

so i think that 'screen space shadows' is something of a misnomer in that the technique it usually refers to is what unity seems to call 'contact shadows' in HDRP.

and i am bound to URP for my project

[marble vigil]

I'm not sure what kind of change you're expecting visually
Your shadows seem very faint and extremely low relative resolution

[marble vigil]

Actually it seems I was thinking of contact shadows, which are indeed called screen space shadows in other contexts

URP's screen space shadows is different, and not meant to cause any visual difference

To render screen-space shadows, URP requires an additional render target. This increases the amount of memory your application requires, but if your project uses forward rendering, screen-space shadows can benefit the runtime resource intensity. This is because if you use screen-space shadows, URP doesn't need to access the cascade shadow maps multiple times.

The Screen Space Shadows Renderer Feature doesn’t affect how shadows look.

[coarse tangle]

yep. that's a poorly named feature. thanks.

[patent stone]

On the thing on the right of the image it is supposed to be the two colours, light and dark blue, on the light blue part there are heaps of lines on it

[ornate tusk]

So if I didn't want my scene to have these kinds of shadows from the directional light, how would I turn them off?

[patent stone]

This would be in your directional lights light component

[ornate tusk]

That's already set to no shadows and I'm still getting that highlight into shadow line

I basically want them to look lit from all directions no shadows

I'm using a full screen shader that is handling the lights for me but I get the soft shadow from the lit material and the hard shadow from my full screen cel shader

For example, this is the basic unlit shader using my fullscreen pass

Then once you make it lit it gets that nasty shadow through the middle

Now the obvious answer is to make them all unlit but then I wouldn't get emissives

[patent stone]

I have no clue i'm sorry, the light shadows was my only suggestion ahaha, does it look the same in gameview?

[umbral bison]

hi i build the same project once without GPU resident drawer feature and once with, the one with the feature enabled has ~15 fps less, isnt it supposed to increase FPS? both URP, literally the same proejct, once with the feature on and once with it off

[soft lion]

Assuming you got it to work in the first place, it's still not that simple. It is indeed supposed to improve performance but it all depends on your game. Let's say you had empty scene with nothing in it, draw call optimizer will obviously not increase your performance if there was no draw calls to optimize. It might just end up wasting resources trying to find things to optimize when there's none or little. Afaik GPU resident drawer is just a form of GPU instancing meaning it is useful mostly in large scenes with lot of similar objects in it

Same way you can't expect occlusion culling to magically improve your fps if you only have one huge detailed mesh in your scene which isn't split into smaller pieces. What happens to your FPS will depend on how much there is to optimize using the optimization method and what is its cost relative to its benefit

[marble vigil]

This is not shadow exactly, but how the lit shaders light up polygons by their direction relative to light
Iirc some of newer URP's unlit shaders do support HDR color for the base map, but if you can't find any it's very simple to make a custom unlit shader in shader graph that includes an intensity multiplier or a separate multiplied emission texture field

[umbral bison]

I understand, in my test scene i had a huge terrain with a bunch of drawn on grass, trees plants and rocks, and a bunch of handpalced objects.

From my observation the feature lost me 15 fps like I mentioned, in what could would this not happen?
for example, if i had more variet objects so gpu instancing would be less effecient, GPU residentdrawer would help in that scenario then?

[soft lion]

Did you place the trees, grass and such using the terrain system or using individual game objects?

[umbral bison]

about 90/10, 10% handpalced id say

[soft lion]

I think the terrain system is already heavily utilizing GPU instancing so the resident drawer might not be able to help on that but if you have a lot of instances of the same mesh as a gameObjects, the resident drawer should be able to optimize those draw calls

[fair yew]

I have an odd issue with Forward+. It seems to be culling some of my meshes based on distance even when visible, and no occlusion culling enabled. Doesnt do this on all meshes and i cant see much difference other than size between them. Does not do this on Forward or Deferred. On Unity 6 .21f. Anyone seen this?

[fair yew]

Posting on discord is always helpful, i seem to always fix it. Its as a result of the small-mesh screen-percentage set too high on the GPU resident Drawer

[umbral bison]

every few sec i get a huge lag spike, might be unity 6 related since it didnt happen in the earlier version, using urp

sometimes its just editorloop, no child, 213mc, empty scene, still stutter

enabled deep profile, now its fixed , even with deep profiling off

wtf, restarted editor, issue is back

[tranquil narwhal]

sup gang

I started this project out as a 2D URP

but I decided mid project I want to use 3D objects

I see my camera's renderer is "Renderer2D"

but I don't have another option for it, neither know how to create my own renderer

halp plz

my 2d objects are always on top of my 3d ones

plz tag me for response

[marble vigil]

You can follow pinned instructions on this channel for urp setup which makes a 3D renderer

[tranquil narwhal]

do you know which one it is?

btw these that are always on top, are sprites

[tranquil narwhal]

do you have the link?

[marble vigil]

It's pinned on this channel

[tranquil narwhal]

yeah... more than a few

not sure which one it is

[marble vigil]

"Configuration"

[marble vigil]

Sprites always follow rules of 2D sorting whether your renderer is 2D or 3D

[gilded mantle]

Hello everyone. I'm looking for a way to make my UI look like... well, this. old monochrome display-style.
Slightly lens-distorted, bloomy, with various shimmering lines and stuff.
I'm new to URP and don't know how to make it properly, post-effects seems hard to apply to UI only.
Shader graphs? render texture? ways i don't know of?

[errant vessel]

Hi guys,
I just upgraded my project to Unity6, but that made my custom universal rendering pipeline script to be broken.

Is there anyone who master on this topic?
I need help to refactor the code so that it works on Unity 6

My custom universal rendering pipeline is from this page:
https://github.com/Unity-Technologies/UniversalRenderingExamples

[karmic iron]

You have to convert it to Render Graph, search up RecordRenderGraph on github/Unity manual and you'll see what you have to do to change it

[errant vessel]

Too bad, I'm very new to this topic and don't have the time learn it...

Also, I just realized that the license is personal and non commercial purposes only, so.... 😄

I guess I'll need to use the official Unity Toon Shader (which has support for Unity 6) then

Thank you for the response btw!!

[karmic iron]

On the topic of Render Graph - trying to get compute shaders working for Post-Processing in it, but not sure if that is possible? According to scripting manual, I need an output buffer, but all I actually want is some TextureHandle references to pass around.

Trying to run my compute shader render pass that just uses TextureHandles and has no OutputBuffer, I get a debug output from RecordRenderPass but nothing shows up in the Render Graph Viewer, it kind of silently doesn't seem to run.
Edit: Got working

[sturdy spear]

Anyone work with depth textures recently? I can't seem to get anything to work

[kind junco]

Hi there. Idk if I am in the correct discord channel. But I have an issue with my 3D model and the material/texture. I downloaded the tree model from the web and it came with leaf textures. I added the .png's to the Base Map and Normal Map but the alpha channel isn't working properly. Any idea how to fix this? Thx a lot.

[ebon karma]

set the surface type to transparent or cutout

[pliant vigil]

anyone know why when I change the name of a render feature it gives a NRE?

this is a fresh project for testing, the only shenanigans is that I converted it to android to test if this all works on android, and then back to windows

then I restarted the program

I tested various things and only the renderfeature name is throwing NREs, none of the other options are

very odd behavior

[pliant vigil]

tested it by restarting unity, it saves the file just fine

so no idea what that's about lol

[lament iris]

I have some 3d components in my scene that never move, and my camera never moves. Is there a way to bake the render or only render those parts once to improve performance?

[lone lantern]

Hi, im wondering how i can make textures tile, but not stretch in URP?

[soft lion]

That's called baked lighting

[soft lion]

Could you give more context?

[lone lantern]

like in probuilder, when you scale the objects, the texture stays the same size and just repeats, but im not using probuilder

[soft lion]

It's up to the UVs to decide how the textures will get placed on the object. Probuilder maps the UVs in a way where the effect you are describing happens. You can do the UV mapping/unwrapping in whatever modelling software you are using. Especially if you are procedurally generating the mesh, you may want to take a look at triplanar mapping shaders which don't rely on UVs but rather the normal and position of each fragment

[lone lantern]

ok, thanks

[modern oracle]

I tried to convert my BRP materials to URP but everytime I do it the objects that don't have the icon in the image attatched turn invisible, please help

[stray jasper]

Im using unity 2D URP and im trying to create a custom render pass that creates a render texture that i can then use inside my shader graph shaders. But i have a few questions:

1. All my sprites have to be on the very same render layer because we use Y-Based sorting. I have 2 types of objects - Trees and lights. Now, my render texture is supposed to be a mask for the lights. So my idea was to draw everything to the texture, where the trees just put '1' in the R-channel and the lights put a '0' in the R-channel. Is this possible to do with a custom render pass?

2. How do i correctly set the render taget? I currently use this:
   ConfigureTarget(renderTexture);
   ConfigureClear(ClearFlag.All, Color.clear);
   but in the frame debugger, i dont see the correct RenderTarget

[lament iris]

I tried that but instead of the normal realtime lighting, when I bake it it looks awful at the area by the plant (the original is on the left)

I also fully generated lightmap uvs for everything here

[nova bear]

You can enable compatability mode to get it working temporarily, but it's reccomended to update to rendergraph

[marble vigil]

You have invalid texel artifacts and missing specular response
Otherwise I'd say it looks better
https://discussions.unity.com/t/lightmapping-troubleshooting-guide/895352
See chapters 5 and 15

[soft lion]

I'd also say it look a lot better

[hearty pine]

Can someone explain shader stripping to me?

Like why do you need to do this. I don't remember built-in taking so much time to cook it's shaders compared to urp

What's different technically speaking and why do you have to exclude your shaders manually as opposed to depending on target platform build and existing materials in project

[hearty pine]

Dead chat rip

[sharp chasm]

How much shaders do you have in your project? As far as I understand variant generation, it makes variants for every possible keyword combination, so the difference may not be noticeable if you have just a few shaders. But I may be totally wrong, if so a slapindaface would be appreciated

And compared to BRP, I guess urp adds a bunch of additional keywords

[hearty pine]

Can't tell as I don't have the last project I worked on on my disk anymore and I haven't used urp since until and was considering trying it again now

I'd guess around ~50? The cooking time was several hours, up to 5 if I'm not mistaken. The progress bar and time estimate would just keep increasing so I left it overnight

[sharp chasm]

omfg thats hella lot of time.

[hearty pine]

Like there are millions of variants

I'm reading it right now and people are building for literal days

[sharp chasm]

does StripUnused help? ik the only chance to check it is to actually build 2 times with different settings but have no other idea how to check if its because of variants

pure logic suggests that's it

[hearty pine]

I'm gonna look into it and in general I'm reading up shader stripping right now

It still seems so weird to me

[sharp chasm]

or maybe you're using lots of inlined shader functions, inlining can increase build time according to internet, but idk how big is the impact

[hearty pine]

The implementation of URP really just seems to be not very good. I can't think of another render pipeline or engine that performs so poorly without manual intervention from the user

Afaik this isn't an issue with built-in or HDRP

[sharp chasm]

afaik URP is basically a default template setup for SRP, but imo these sick build times indicates that they made something really wrong with it xd
and writing srp from scratch feels too much hassle to just decrease that build times

anyways, im probably not the best person to ask about urp under-the-hoods so i'll let pros elaborate

[hearty pine]

I don't think most people even know this channel exists

[sharp chasm]

Conclusion - don't use urp
Jk, unfortunately there's no support for ECS in built-in. Also I've read somewhere that urp has to be setup carefully to not harm performance. Feels like these two things kinda conflicts with each other

I'm starting to think that urp is just a reference to jump into writing srp

[marble vigil]

In my experience the two biggest causes is having a lot of rendering features enabled (which by default are) as listed here: https://docs.unity3d.com/6000.0/Documentation/Manual/urp/shader-stripping.html
As well as having a lot of different shaders/materials
Often I end up with a lot of clutter when testing various things so it's often quicker to make a new stripped down project to import the necessities into as a .unitypackage for building

[hearty pine]

Look helpful, alright ty

I wish they actually explained what some of those features do so it's easier to know if you can disable them

Fast sRGB to linear conversion, Accurate G-buffer normals, Render Pass and Additional lights specifically

[marble vigil]

They are settings in the URP Asset and URP Renderer asset so the explanations are in those articles
https://docs.unity3d.com/6000.0/Documentation/Manual/urp/universalrp-asset.html
https://docs.unity3d.com/6000.0/Documentation/Manual/urp/urp-universal-renderer.html

Additional lights are any punctual light components besides the directional light, that one is not clearly explained there

[floral raft]

guys please i need help

i had some materials which where pink, i decided to install universal render pipeline to convert the assets, i did that now most of my project is pink and i don't know how to revert

[dreamy stratus]

Did you only convert the assets ? Didn't you also assign URP as the current renderer ?
Else, no, there is no URP to BuiltIn converter, you would have to revert the materials manually. It is always recommanded to make a project backup when doing such big changes.

[floral raft]

thanks

i'm restarting

[vast panther]

Is there a way to convert materials back from urp? I want to move to the usual post processing

[marble vigil]

See just a few messages above

[manic nacelle]

Hello! Why does my lighting look like this? is there any way to get it smooth without all this jagged noise?

[marble vigil]

If it's realtime light you can enable dithering on the camera to alleviate it
If you're also using the deferred rendering path you may need to enable accurate g-buffer normals for more precise gradients
If it's a baked lightmap, the issue may be lightmap texture compression

[manic nacelle]

Its baked, using the forward renderer and the lightmap compression is set to "none"

[tranquil narwhal]

^ sup gang, after that~ Not sure if this is the correct channel for it

I have post processing, but even when disabling it they still blur out on distance

everything is unreadable at distance, how should I work that out?

the card description or stats are very blurry

[tranquil narwhal]

plz tag me for reply

I tried playing with these but still no luck

[marble vigil]

It might just be the limit of the color depth of the lightmap texture
Such flaws are best concealed by giving the walls textures or other surface variance

[manic nacelle]

Alright will try to improve the textures

[marble vigil]

It does not seem like a blur, nor anything to do with post processing, rather the effect you get when scaling down a texture/image that has no mip maps enabled

You can improve it by enabling bilinear or trilinear filtering and/or increasing aniso level
The result will be less distorted, but it will be blurred that time

[tranquil narwhal]

what about the text?

it's a text mesh pro object

is there any way I can make the text look sharp?

like it does when in the canvas

[marble vigil]

Iirc TMP text should be antialiased pretty much in all situations by default
So I guess something else could be wrong
Make sure you're previewing the Game window at 1x zoom when testing for this

[tranquil narwhal]

yup

I tried in build too and it looks blurry

it's okay if the card texture/description image is not 100% readable

but I would love for the TMP to look as sharp as possible

I think I figured it out, I changed the TMP material from

Distance Field --> Distance Field SSD

and it's a lot sharper now

👌🏼

[tranquil narwhal]

thx for that, you made me look the right way

[umbral harbor]

Does anyone know if/ how it is possible to customize/inject into the URP lightmapping algorithm?

If it isn't possible, is there some way to view the lightmap algorithm source code?

Currently running into the problem of baking toon lighting, and I might be able to pull some shenanigans with a meta shader pass (which, correct me if I'm wrong, just changes how a surface looks to the lightmapper) if I know how the lightmapper works in detail and editing it isn't an option.

[cloud scroll]

i have thousands of windows that i want to light up... on a building.. the windows all share the same mesh data and material. Whats the best method for doing this? I've tried... static batching, material property blocks (which i think the docs say, not to use because that breaks batching), instancing... i have yet to try a shader because im not exactly sure how to turn them on/off using that method...
..can someone point me to a good idiots-guide-to doing this?

[karmic iron]

By light up/turn on or off, you mean like there's a light inside? If so, would suggest looking into something simple like just using a shader that supports emission and changing their emission value, that way combined with bloom they could look "lit"

[marble vigil]

The preferred way in URP is to swap to a different material, or a runtime material instance if you need the material properties to change programmatically

[cloud scroll]

yea this is the method ive had most success with so far.. the problem was getting them to actually batch, instead of having thousands of batches.. but it appears like ive managed to get it work.. i think.. its down from 8000 batches to 150ish lol

[marble vigil]

You don't have to get them to batch because SRP Batching optimizes draw calls even if they can't be batched

It often beats gpu instancing in efficiency also, in scenarios that are impossible for gpu instancing due to different materials

https://docs.unity3d.com/Manual/SRPBatcher.html

[cloud scroll]

i'll check that out in a bit, i just know i gained 100fps in the editor from all my faffing about, which is nice...

[marble vigil]

It's a bit of a pitfall since SRP batcher quietly made most of unity optimization guides made so far more or less obsolete

[cloud scroll]

so it's gone from 'not great fps' to 'better' -- so im happier, since it looks worse lol... but i'll read that and work out where i'm going wrong cheers

[marble vigil]

There's still a lot of techniques for optimizations, but you have to be analyzing different metrics than draw calls

[cloud scroll]

ok, so.. 172 batches is not horrific then? -- i mean i dont know the fps seems 'fine' to me right now...

..you know what it's fine, its improved.. it still works, im happy.. i'll just keep plugging away and read what you've linked (ive probably read it twice already) and maybe ill be back asking more dumb shit. cheers

[marble vigil]

You should forget about the batch count, and preferably the stats window entirely when doing any serious optimization

Use analysis tools like GPU profiler and frame debugger
You'll want to do profiling in a build when you need accurate data

There are external GPU-specific profiling tools also that can produce more accurate breakdowns than the unity editor can
But mostly you just need to understand how much stuff you're rendering, how long it takes and what rendering features you're using and then measure their rendering cost

[cloud scroll]

ok cheers, i guess i am being premature with my optimization but i wanted to check i wasnt doing it horribly 'wrong' in the first place --as i said im happy for now, its 'playable'

[steep chasm]

Im looking for a way to render a TMP mesh in front of my other 3D objects - I found a few solutions describing something of this sort but I dont see how to translate this to URP - at least Im assuming me using URP is the reason these camera settings dont show/look differently for me

[marble vigil]

URP uses the Render Objects renderer feature for this type of task

[steep chasm]

can you elaborate on this just a tad? the example in the documentation is rather overwhelming given what I wanna do is a lot less complex

[marble vigil]

The short version is that the renderer feature renders objects on a specified layer, at a specific point in render order, with some extra options if needed

If your text is on that layer, and you set the Render Objects to render it after transparents, it should appear in front of everything

Just be sure to disable that layer from Renderer Layer Mask if you don't want it rendered before the Render Objects renders it again

[marble vigil]

Unlikely to be possible
How would you edit it anyway? Toon lighting isn't usually compatible with baked lighting for practical reasons

[umbral harbor]

Right now, I am planning to mostly be simplifying stuff a lot. I don't really care too much about the extra detail that can be provided from lightmaps, I just want to reduce the number of dynamic light sources in my scene. I have made a toon lighting shader that works with multiple light sources for dynamic lights, and I essentially just want to be able to bake the diffuse from that shader into a lightmap.

[steep chasm]

Im a bit confused still, am I supposed to add this to an existing rendererasset or make a new one with the settings to render certain layers in a different order?

[steep chasm]

I seemed to have gotten it to work in some way - the text now always renders on top the 3D object it's a child of, but not other 3D objects

[marble vigil]

The renderer must be in use to see the effects of the renderer features in it
You'd have to look into some documentation and or tutorials to understand the system, even if the task is simpler than most of the examples

[steep chasm]

yeah no all that I got working

[steep chasm]

just this last bit is giving me trouble

[marble vigil]

Right now, I am planning to mostly be

[normal sparrow]

would URP be the preferred renderer pipeline for WebGL from unity 2022+ or would that still be standard pipeline? For performance reasons? I thought the performance is pretty close from 2022+?

[marble vigil]

It can vary a lot by what stuff and how much of it you need to render, and what performance you're targetting
I think URP is easier to use and does a lot of the optimizations for you
But if you're really strapped for space and performance in your target device, from what I hear BiRP can be squeezed tighter if you handle the optimizations yourself strategically

[normal sparrow]

Thanks a lot, birp? Is that the pre-urp one?

[marble vigil]

BiRP meaning the built-in render pipeline that the project has if no scriptable render pipeline is installed
It's not the "standard render pipeline" since it's no longer the standard, despite being default
And it'd be too ambigous with the SRP acronym

[digital plaza]

(Forward+) As of right now, a custom RenderPass of mine uses CommandBuffer.DrawMesh. My issue is that the mesh gets drawn to every camera in the scene, including overlay cameras that are a part of the main camera’s Stack. Is there any way to limit the cameras that the RenderPass renders the mesh to?

[pliant gull]

Hi, I bought this asset pack (image 1) but none of the materials seem to work or show up (image 2 and 3(pink ones don't have material at all but the grey ones do)) is there anythIng i can do to make this work again without refunding? I used the same editor version on the thing (unity 2021.3.35f1) and URP but it still doesn't work and their discord server is dead.

Thanks in advance.

(and for the grey ones it wont let me change this)

[sour nest]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@7.1/manual/upgrading-your-shaders.html Trying to follow these instructions but the "Render Pipeline" option isn't present?

2021.3.44f1 if it helps

URP is installed and enabled

[sour nest]

Tried to convert it using the winodw

and it broke

so I'm "rebasing" (in git terms) to a URP project and moving my game inside

I haven't touched settings so I should just need to copy my scripts and assets over

[tranquil narwhal]

sup gang

you got this my friend

I have "OnMouseOver" on my card objects

and buttons on my canvas

when I try to press those buttons, it prioritizes the "OnMouseOver" of the cards and drags them around

which closes my menu

I would like for my Canvas to block whatever is behind it

[haughty garnet]

OnMouseOver uses a physics raycast while the canvas uses a graphic's raycaster

[tranquil narwhal]

nice

what should I do then?

put a....

OnMouseOver()
{
if (IsPanelOpen) return;
//Do card stuff here
}```

[haughty garnet]

Is everything here on the canvas? Then consider using IPointer interfaces and crew

Otherwise yeah, need to check against each raycast selection

[tranquil narwhal]

they're 3d objects, not in canvas

the one I'm using mouse over on

[tranquil narwhal]

#🎥┃cinemachine

I wonder what camera I should use in that case

I want a camera that I can move with W and S

that goes from point A to B like in the curve there

[haughty garnet]

Actually, IPointer does work with non-UI objects too, so you do run into a similar problem so that leaves you with checking a method like :

EventSystem.current.IsPointerOverGameObject()```

which if true means it's over UI elements despite the very vague method naming.

[carmine gyro]

Hello, I'm experiencing issues with a certain shader which uses URP. It's called Saturate, and it glows an object to be white when set.

The problem happens when URP ignores the alpha channel (and even dyes the alpha areas red). This doesn't happen in Scene, only through the Camera.

Here are images of the shader (which works in another project flawlessly) and the images of the object using the shader in question:

Thank you for your time.

[sinful gorge]

Is it post processing? If so, in the URP settings you can enable the alpha channel for PP

Or is it an UI shader?

[carmine gyro]

unfortunately I don't see anything for it in my pipeline asset's settings. I tried looking in both places:

[sinful gorge]

Ah then that's from a more recent version. But contact the asset developer, as this is an issue with their asset @carmine gyro

That probably gets a better response

[carmine gyro]

oh alright

thank you!

[north glen]

i want to get my transparent roof to affect the lighting inside the house, i make the roof material transparent and the light travels right through!, how do i get the transparent model to affect the lighting inside? i have made the alpha 200

[sinful gorge]

Maybe cull the roof from the camera? Layers could be great for this (like a Camera culled layer)

[north glen]

?, how would that affect the lighting?

on the floor?

[tranquil narwhal]

I did try it and that didn't work but

let me try it again

it was always returning false or true, I don't remember

I was too sleepy xD

[tough burrow]

I'm trying to use a few decals on my game, but they seem to be very transparent, even though (I think) I haven't messed with the decal shader, is there something I missed that could solve that? (opacity is maxed out, btw)

[vagrant jackal]

It seems that post processing is working different in Universal Render Pipeline compared to the built in version. How can I make certain objects be effected by the Volume framework? For example only make certain objects glow

[halcyon kraken]

I also want to do this. There are some ideas in this thread, but I was hoping for something simpler like layers. https://discussions.unity.com/t/assign-post-process-volume-to-a-objects-on-a-layer/872050/6

[vagrant jackal]

One solution would be to increase "threshold" under the "bloom" effect, so objects only glow if they emit more light than the threshold, but its not ideal

[halcyon kraken]

Yeah that and maybe manually modifying emissive dynamically

[errant cloud]

Hello,
Not sure where this question should go exactly, but has anyone managed to get Billboard-type shaders to work with quads displayed via the BatchRendererGroup API?
I'm guessing there are some shenanigans due to how BRG handle Transformation Matrix data per instance, which Billboard-type shader need to manipulate, but I'm not sure how to fix it.

[plucky sapphire]

Hello,
i have a few effects that could benefit from having a texture with all the sprites drawn so far, but only in specified sorting layers.

Is there a way to write sprites to separate texture, e.g. separate the textures per sorting layer?
current sorting layer texture only uses foremost sorting layer, while i don't want to use the far background layers. also would like to use the texture with whatever is drawn to it so far

Thought i could do it with CommandBuffer but seems they dont work in URP

Thank you in advance

[vagrant jackal]

i added a second camera as an overlay that only handles the bloom effect

[halcyon kraken]

Nice, I'll give this a try. I am guessing you used layers to choose which objects are rendered by the overlay camera?

[opal pine]

How can I achieve an outline effect on certain objects? Like how unity outline's selected objects in the editor?

[vagrant jackal]

Yes, first I added a second camera to the main camera and positioned them so they overlap, maintaining a fixed relative position to each other. For the second camera, I set the Culling Mask to only render the "Bloom" layer and did the same for the Volume Mask, ensuring it only affects the "Bloom" layer. I also set the camera's Render Type to "Overlay" and added this overlay camera to the main camera's settings. For the main camera, I reversed the process by excluding the "Bloom" layer from its Culling Mask so it renders everything except that layer. Lastly, I assigned the objects I wanted to have the bloom effect to the "Bloom" layer. To apply the effect, I created an empty GameObject, added a Volume component to it, and set its layer to "Bloom."

[halcyon kraken]

Cool, this worked out for me. I was able to get a "blur" layer working

[vagrant jackal]

nice

[whole raft]

Hello, does anyone know why in Unity 2022.3 and URP 14 the decals may be working in Editor but not in Build ? (with Screen Space)

[brazen ember]

does anyone know how to make an unlit color material transparent?

[marble vigil]

Create an URP Unlit material, set material type to transparent, decrease alpha of base color or assign a base map with alpha

[brazen ember]

i have an unlit color material with an alpha set to 0.5 then set it to a mesh renderer and its not transparent

any idea why?

Settings for the mesh renderer

[iron compass]

Do you have discord on the PC you are working on?

[brazen ember]

yes

[iron compass]

You may want to try making screenshots on that pc directly.

Also there is no mesh on that object you are showing and all other settings make no sense either.

[stable island]

Hi I want to outline a selected object in the scene. I am guessing the easiest way is to render that item into the stencil buffer and use a post process to outline? It may have semi transparent elements which should be solid for outline. However I have never used the stencil buffer before!! Anyone seen examples of this or a better way to do it?

or maybe it is command buffers actually... or render pipeline :/

[iron compass]

The easiest way is through a saturated blur effect as exemplified here. This is only recommended for thin outlines (1-4 px). More complicated techniques for thick outlines exist (google). https://github.com/Arvtesh/UnityFx.Outline

[stable island]

thanks - that goes back a few Unity versions but will give it a go

[iron compass]

its got an API incopatibility, but the principle is still the same. Easy enough to update yourself.

[fleet orchid]

what's the way to find out what is taking the gpu render thread time? I guess I want something like for the CPU where I can see how many ms what things take.... I know of the frame debugger but so far as I can see that doesn't say which call is taking the time...

[hearty pine]

Wow this channel is dead dead

Anyway if anyone knows how to use EnqueuePass in a similar fashion to old command buffers and set the queue please let me know. Specifically similar to how you'd set Rendering.CameraEvent.Before/AfterSomething to get it to draw in correct order

Alright I found it

[dry willow]

Renderer feature or add methods to the static events in the RenderPipelineManager class

[hearty pine]

You need to modify the built-it property of your custom render pass (type ScriptableRenderPass)

customPass.renderPassEvent = RenderPassEvent.BeforeRenderingOpaques;

Right after your create it and before you enqueue

I should put all this obscure information in a blog or something I swear

[floral sundial]

What can cause this black line flicker? it happens every few seconds (im using URP)

[marble vigil]

A shader produces a NaN result

For example by dividing by zero

[floral sundial]

interesting, how would i find which one is causing it?

[marble vigil]

Usually it's as simple as clicking on the thing to select it in scene view
Or disabling objects until only the problematic one remains

Kind of looks like it could be the skybox shader rather than any object but it's hard to tell when the video's fps is less than one

[karmic iron]

If I had to bet on one thing I'd say it looks a bit like a bloom NaN

[noble stirrup]

Hi, my friend with an rtx 2060 keeps trying to bake a lightmap, but either unity crashes or his entire gpu crashes. His gpu is fairly new and can play many games well. These are the lightmap settings

it is a fairly large scene so im not sure how to go about baking it

[strong aspen]

for large scenes is better to use APV's and disable realtime lighting

[twin mulch]

Im getting 20FPS higher ( lower CPU ms as well ) in deferred pipeline vs forward + in the new fantasy kingdom sample, despite the new GPU resident drawer cutting draw calls and triangles... Is this to be expected?

[clear goblet]

What platform and hardware are you running on ?

[twin mulch]

MacOS in editor, M3 Pro @clear goblet

[clear goblet]

That would be kinda expected I would say.

[twin mulch]

How about your side? Is GPU resident drawer giving you better CPU ms? @clear goblet

[clear goblet]

I worked on the project and GRD gave us better cpu ms across all platforms. Deferred was never a consideration since of the mobile requirements of the project.

[twin mulch]

Guess, I should be looking forward to Deferred+ next year 😅

[clear goblet]

Keep in mind that deferred is not always better than forward.

[twin mulch]

Will all these still work in the new unified pipeline anyways? Unity 7 seems like a big jump

[clear goblet]

I would hope so ☺️

[twin mulch]

Hope so too! Looking forward to it, many popular and big features

[meager sedge]

is there a way to make the shadow caster 2D component follow the shape of my character more closely when using sprite renderer as the casting source?

Does anyone know if webgl build supports URP decal projectors? Desktop build looks fine but can't see the decals on webgl.

These kind:

[haughty garnet]

Double check that you're using the correct render profile when changing to webgl

because they do work

[thorn lake]

Thank you!

[soft lion]

Yes, mobile can't handle that high resolutions too well

[echo fractal]

I really need your help. I migrated to Unity 6.

I use 2D and 3D and URP, before Unity 6 :

• When moving to the front of a sprite, a trigger put the player behind it physically, so the sprites was upfront him, he was hided by the sprite.
• When leaving the trigger, he's at the start position, so he's no in front of the sprite

After Unity 6 I noticed that moving physically the player don't work anymore, the only way to put him in front, is to change the Order in Layer to negative, but the sprite will always be behind the player, even if he's physically behind that sprite. Do you have any idea ?? Here's what I need to replicate! Thanks!

[twin mulch]

Actually even on Forward+ but with GRD disabled i get 10 FPS higher + 1 CPU ms lower than with GRD... @clear goblet

Batches and triangles have been reduced by a lot, but get worse FPS? hehe

[clear goblet]

How are you measuring the fps ?

[twin mulch]

Unity Stats

[clear goblet]

I never trust the game stats panel with SRP’s if you press tab a stats panel in the project should open up

Also having scene and game view open at the same time muddles the stats

[twin mulch]

I gtg for now be back in a few hours sorry

[solar patio]

Hi, I'm new to URP (used builtin a lot) and I was looking for a blur effect on UI and not 3D or on screen space overlay type. I tried tutorials and other free assets but they are all not working.

[mystic delta]

If you want effect on entire UI and and not just the font you'll have to put UI into camera space to be affected by post processing. Also render it with separate camera if you want only UI to be affected.

[solar patio]

Right now I'm using depth of field for blurring out

But I was looking for something that blurs the UI as whole or parts of it

Like if I add a material to an image it blurs (I have a similar asset in builtin)

[noble stirrup]

hello, why is this grey cube that represents asphalt not getting lit?

[twin mulch]

Ok I tested it with the provided stat panel on the canvas

Fantasy Kingdom Sample GPU Resident Drawer (GRD) Test - MacOS in Editor URP Forward + M3 Pro

GRD on : FPS ~73 , CPU ~5.5ms GPU ~ 1.0ms

GRD off : FPS ~81 , CPU ~6.1 ms GPU ~ 0.2 ms -1.0 ms

😅

[clear goblet]

Well I think fps should be higher with grd on. Submit a bug report.

Does the gpu tine increase ?

[twin mulch]

GRD off has a strange GPU time, with it going from 0.2 to 1.0 in a loop

GRD on holds steady ~ 1ms GPU time

[clear goblet]

Those timings are way too small. Submit a bug report maybe something is wrong with the mac platform or Metal drivers or something

[twin mulch]

Its uploading the bug report now

Yeah, but regarding Unity on Mac, performance has been excellent thus far @clear goblet if GRD boosts it even more, that would be amazing

[naive holly]

Hello, I switched to Unity 6 LTS yesterday, and I was wondering if anyone also had an issue when having 2 cameras in a scene, it works perfectly fine in the editor but on the Windows build after the Unity splash screen it stays on the splash screen background color... The scene seems loaded though, there's sounds and everything seems to work but there's nothing visually, just a gray uniform background

[cunning surge]

hello, I was trying to learn render graph stuff with the urp samples but for some reason its not working properly. the BlitWithMaterial Render Feature when set to afterRenderingPostProcess render event doesnt work or show up in the frame debugger but when set to after rendering transparents or earlier it works fine and shows up. the render feature by default is set to after rendering pp. anything set to before rendering pp or after pp seems to not show up in frame debugger. I am sorry if this is something simple or known, please help out if you know.

is this happening because of how render graph can choose what to run and what not to for optimisation?

I have the blur render feature example from unity too and that runs fine and shows up in most events except for something like after rendering

[sinful gorge]

Try a dev build and check for errors
And definitely file a bug report

Switching APIs (dx11 or dx12) could also help

[hoary hornet]

Is it possible I accidentally deleted something important? I'm trying a shader tutorial and everything works great until it turns into this pink mess and that's what shows in game despite looking good until then.

I figured part of it out.. It's because I have nothing here. If I add it then this shader works and literally nothing else does.. hmm

[cyan talon]

Then your project is not fully set up to use the render pipeline, and the above shader is

[hoary hornet]

I just copy/pasted a shader that is working and rebuilt it from there. Game releases Monday.. lol 😅

[feral cairn]

Any thoughts on how to start converting this into the new format using Render Graph?

Some docs say for example to still use OnCameraSetup after converting (https://docs.unity3d.com/6000.0/Documentation/Manual/urp/upgrade-guide-2022-1.html) even though it's obsolete and I just don't understand if there's an error in the docs or what

[dry willow]

There's a page here with an example, https://docs.unity3d.com/6000.0/Documentation/Manual/urp/renderer-features/create-custom-renderer-feature.html
I know there's some examples in the discussions thread here too
https://discussions.unity.com/t/introduction-of-render-graph-in-the-universal-render-pipeline-urp/930355

[feral cairn]

Thanks, yeah, I've read through those and did some of the examples like the blur pass etc. I think I'm just slightly too noob to really understand what's going on to make anything custom and not just follow the tutorials

[maiden depot]

I am having a problem with lens flare for SRP. If I use Allow Off Screen, flare will "clip" through the walls, when it is slightly off screen, even though there is clearly a wall between camera and flare. I tried to experiment with occlusion settings, but couldn't get it right, can someone help?

[stone mesa]

Hi, im kinda new to Unity, done a few projects. I have a problem with Synty fantasycharacterhero and unity 6, it says that the asset is compatible with URP but when i try to use it in unity all the textures are magenta

when i import the asset i get alot of these messages, "A polygon of Mesh 'Chr_Hips_Female_06' in Assets/PolygonFantasyHeroCharacters/Models/FixedScale/ModularCharacters.fbx is self-intersecting and has been discarded." do i need to somehow allow self-intersecting in my project?

[naive holly]

Thanks, found out that the issue could easily be fixed by just enabling the render graph compability mode

[sinful gorge]

Please do still file a bug. The normal mode should perform better and should work, and if issues aren't reported they won't be fixed

[naive holly]

Okay I'll do that

[placid escarp]

Hello everybody anyone knows why this could be happening? https://gyazo.com/d491538e51e1f5dadbc9f54e4b9a6d5f
Its really weird, its happening inside game and editor aswell

It happens randomly in certain meshes from certain positions and angles, already checked normals, z fightning, camera culling settings, but i think its nothing about that because it happens randomly to certain meshes

[sinful gorge]

Are you sure it is not ZFighting?
And how many realtime lights does your scene have? Could it be that you are surpassing the additional light limit?

[keen willow]

I have a main camera and a camera that gives me Bloom. I want to put pixel perfect camera components in here, but I have 2 cameras, so it doesn't work, how do I solve it?

[placid escarp]

Yeah 100% sure, double checked in blender and also if it was z fightning it happened more than it happens but its random

@haughty cliff

There is a light limit with deferred lightning?

[sinful gorge]

There is a very big one haha
If you surpass that your PC probably is dead (;

Is Unity up to date?
Any screen space effects running?
Did you also double check for a random cube in Unity? Happened to me before

[placid escarp]

I have a lot of lights, but camera has a really low max distance of rendering (Rooms are really small) like 70 lights approx
No screen space effects running rn, unity up to date yes,.

i temporarily just solved it by activating GPU Instancing in that material, maybe its showing up again because its non sense lol

[maiden tundra]

What causes this type of noise? Both in scene view and game view.

[soft lion]

I'm having really hard time trying to figure out what I'm looking at here. Regardless my best quess would likely be SSAO which is enabled by default

[maiden tundra]

Maybe this is clearer. The gray is the floor and the brown is a wall, perpendicular to the floor. SSAO sounds about right.

[soft lion]

Try to disable it and see whether the same happens

Being a screen space effect it's working with very little information and is prone to many artefacts. The default settings may not work very well on your specific case so might be worth playing with

[maiden tundra]

Default size cube and sphere also has the effect. Turning off SSAO did indeed solve the issue. Thanks!

If you don't need ambient occlusion, you shouldn't obviously use it to begin with but if you do, you should be able to reduce the noise by changing the SSAO settings

[maiden tundra]

Yeah setting the quality to high made it better. I'm new to URP, so I just had to get accustomed to where to find the settings for it. Thanks for your help 🙂

Anybody have any idea why im having issues trying to get multiple cameras to work with Unity 6 Render Graph enabled? I upgraded my project to Unity 6 and am trying to get Render Graph running (I had never wrote any custom passes or anything, so I figured it would be pretty simple). Anyways now im getting a grey screen and these errors if there are multiple cameras in the scene. I need multiple cameras in my camera stack for overlaying the held item and other stuff like that. Even if I just put a normal camera in as a second camera (not an overlay camera) it is breaking, but when I disable every camera except the main camera it works fine.

I got to thinking and was like "hmm seems like it would be anti-aliasing" anyways disabling anti-aliasing in my Render Pipeline asset fixed it

which is strange

[sinful gorge]

Definitely seems to be a bug, pleaese report it. Looking at the errors, it seems that UI Toolkit has not gotten the proper fixes yet. Are the packages up to date? (check changelog, not just the package manager)

[pale roost]

I built the game with Anti-Aliasing (MSAA) enabled in the PC_RPAsset, as well as Anti-Aliasing (SMAA) enabled in the Main Camera. After building and launching the game, I experienced the same issue.
It turned out that the problem was caused by a conflict between the two anti-aliasing methods. Disabling MSAA resolved the issue.
This might not be directly related to your situation, but I hope it helps.

[ebon quartz]

Hey guys what could be causing this Z-Axis aligned reflection/highlight on all my materials?

[autumn cobalt]

yeah, im on the latest version of everything

this does kinda suck though because now I just dont have anti aliasing

wonder why im getting this when im not even using TAA

[sinful gorge]

Checked both camera and all quality tiers?

[autumn cobalt]

yes

[sinful gorge]

Hmm weird

Honestly I have no idea without working on the project

[autumn cobalt]

yeah idk

but its spamming my console and its kinda annoying

project will probably end up in the graveyard anyways 💀

[marble vigil]

Tbqh camera stacking is not the greatest option for a viewmodel
I would instead prefer rendering the objects on top with Render Objects renderer feature, or the very simple squashed mesh technique

[autumn cobalt]

gotcha

[umbral harbor]

I'm having some trouble with shadows when trying to add Forward+ support to my shader. In Forward, I used TransformWorldToShadowCoord to get the shadow coordinate and passed that into GetMainLight in order to get the light's shadow attenuation stored in the returned light struct. In Forward+, this seems to cause issues, as the shadow stretches, squashes, and changes shape when moving the camera. I think this has something to do with me incorrectly handling shadow cascades in forward+, as it only seems to be an issue on cascades higher than 1. I've been having a lot of trouble finding much information on Forward+ shaders, so if anyone has pointers on where to look for how to handle this properly, it'd be greatly appreciated!

Hello,

I recently initiated a new project using the Universal Render Pipeline (URP) that includes a terrain and some vegetation.
In play-mode I have observed some kind of flickering, particularly in distant areas, which appears to be related to anti-aliasing. I experimented with various anti-aliasing methods, but the default Temporal Anti-Aliasing (TAA) exhibited the least amount of jitter on my display, although not fully getting rid of it sadly.
Despite adjusting numerous quality and render pipeline settings, I have been unable to identify the cause of this jitter or find a solution to resolve it.
Could anyone provide guidance or suggestions on how to address this issue?

For anyone interested in adding surface properties (for example to do advanced lighting effects), here's how to add a new gbuffer to URP so your new surface properties work in Deferred Rendering: https://discussions.unity.com/t/adding-a-gbuffer-to-urp-example-project/1541024

[lethal panther]

I'm so confused... I got a basic greyboxed level (that I use to test out my player controller), without GPU Resident Drawer, it hovers between 220-250 fps. If I turn GPU-RD on (and the bells an whistles), it dips down to 130-150. Tried with/without Gpu Collusion Culling, SRP Batcher, Dynamic Batching, Static Batching... doesn't really make a difference. Even a brand new project, without GPU-RD : 480-500fps... with it, around 380-430

Am I missing something here? Do i have to set the meshes to some variant of static or something?

[signal fractal]

This shader essentially just replaces the metallic and smoothness input with a 0 if the "Use PBR" boolean is false. My plan is to use two different materials depending on the platform. Will Unity generate a more performant version of the non-pbr version of the shader, or is it automatically optimized, or is there something else I have to change in order to create a more optimized non-pbr version of the shader?

[sinful gorge]

If it's from the main light I suggest looking at the URP custom Lighting on GitHub

[sinful gorge]

Interesting find. Was static batching also disabled? There is a warning for this in the URP asset if not.
Is this in Unity or in a build?

Bug reports are always appreciated if you find big ones. Occlusion culling could have some overhead, but RD should not have so much afaik

[sinful gorge]

Built in shaders do optimize depending on each setting.
In Shader Graph it depends how you make it. If you use keywords directly it should use static branching. If you use booleans, it might not

[lethal panther]

Yeah tried with static batching on or off. Made no difference. Could be specific to Metal on an m1 max (and it's in editor). Didn't try building tbh

[sinful gorge]

If you can make a bug report the Unity QA team can give it a go. I haven't encountered issues with it yet on Windows

[lethal panther]

Is there some guide that tells you all the options to turn on/off as per Unity's recommendations? There's quite a few options and the URP template doesn't set them.

[signal fractal]

Alright, so Keywords do the trick, but does Unity optimize the shader if I just set the metallic and smoothness to 0, or do I have to tell it not to use environment reflections and specular highlights somewhere?

[sinful gorge]

0 should be very fast, sadly there is no simple lit version

[sinful gorge]

Sadly not

[signal fractal]

Perfect, thanks

[eternal hawk]

Hi, has anyone faced such a compilation issue when building game for release in Unity 6? 😄

[eternal hawk]

(updated from 2023.2 and building on Windows for info)

[fierce spade]

Hi, sorry to tag you, did you ever found out a fix that doesn't requires disabling MSAA? I'm experiencing the same issue with my 2 camera stacks

[autumn cobalt]

I ended up just getting rid of the camera stacks

Honesly was good optimization when I didnt really need them

I was able to just find way less expensive ways to do what I needed to them for

[fierce spade]

What way is that? i'm curious to see if i can use that on my FPS (i have a camera for rendering the first person model and other for the environment)

[autumn cobalt]

Ended up doing this

[fierce spade]

Thanks, i will take a look

[autumn cobalt]

[umbral harbor]

In case anyone is looking at this in the future, managed to fix this though I'm not 100% how. Best guess is that upgrading between the unity versions that I did changes some stuff about shader graph when the project is being updated, and I was working on an asset copy and pasted into a newer version from an older version. Copy and pasting everything into the shader that was in the project when it was upgraded fixed things!

[signal fractal]

I set up a boolean keyword for whether to use PBR, but how do I change it based on the platform? Is there something built in or do I just have to set up two different materials and switch between them?

[sinful gorge]

You can set it via C# in Awake or in the build process

[kind swallow]

Out of curiousity, what's usually the more performant option for adding pixelisation to a game between using the URP Render Scale or using a Render Texture?
Currently, I use the former but may need to use the latter due to a fullscreen shader being affected by the render scale.

[ebon karma]

Fullscreen Shader

[kind swallow]

So Render Texture has the better performance?

or do you mean to use fullscreen shader for pixelisation since it has better performance?

[ebon karma]

I think the shader will have better performance

[marble vigil]

I believe render scale is the cheapest, but you're stuck with the settings it gives you
The next best thing is a low resolution render texture, and while you pay the draw call cost of inserting into the render process, you can also freely determine the resolution and aspect ratio, though you may need to create or modify the RT textures at runtime to adapt to different user monitor sizes while keeping the resolution consistent
The least efficient way is to render a full resolution RT texture and then pixelate it in a shader, though with that method you can get absolute control over the pixelization effect and bundle other shader effects with it if needed

[stray jasper]

does 2D URP have a way of getting a Depth buffer that i can access in shader graph?

[deft stump]

Any ideas what can cause this noise on textures? It's way more apparent on the edges of meshes.
URP, the light is mixed

[soft lion]

My best guess would be SSAO (Screen Space Ambient Occlusion). It's enabled by default

[deft stump]

Yep, this is it. Thanks!

[slim hill]

GPU Resident Drawer introduces some flat overhead. So it's expected to have a bit worse perfs on something like an empty project. It should however scale much better when you start throwing stuff in your world. If you continue to see such difference for heavier scenes then that's a bug and should be reported. I would say 250 -> 150 fps is a bit shady.

You shouldn't need to do anything particular to setup GRD. Just enable it from the RP settings, set BatchRendererGroup shader variants to "Keep All" like the engine asks and that's it

[slim hill]

I've already seen this. Are you building player for PC with Vulkan? At least I know an issue with similar symptoms is known and assigned to someone in my team

[ebon karma]

show it

it's probably the camera jitter, not the pixels

[marble vigil]

There's no need to crosspost
The root of the problem is that you lack the experience/care to follow the instructions we tried to give
